Subject: Help!: IRC by mopac
-------------------------------------------------------
####################(questions)########################
Dear all,
I'm searching the structure of the transition state with
mopac for the reaction type,
olefin + carbenium ion ---> (TS?) ---> carbenium ion (1)
My previous try for the reaction,
H H H H H H
| \ / | | |
H-C(+) + C=C ---->(TS?)----> H-C-C-C(+)
| / \ | | |
H H H H H H
gas-phase gas-phase
methyl ethylene primary propyl
carbenium ion carbenium ion
has been found that there is no transition state, thanks to
great help from many CCLers, since the gas-phase methyl
carbenium ion is too unstable.
Actually I'm dealing with more than 100 reactions which have
the reaction type written in (1). Therefore, I tried with
other reaction, which contains more stable species, i.e.,
H
| H
H H H-C-H HCH H H H
H | H \ / H | | | |
HC-C-CH + C=C ---->(TS?)----> HC-C--C-C-C-H
H + H / \ H | | + |
H H H H H
secondary
propyl propene secondary 2-M
carbenium pentyle carbenium
Searching the TS in this reaction, I followed the suggestion
by many CCLers, i.e., try to get the TS structure by the
following steps instead of using SADDLE calculation:
1. Try the reacion path calculation in mopac and save the
structure that contains the highest energy level.
2. Refine the structure at highest energy level with key
word, NLLSQ, or SIGMA, or TS.
3. FORCE calculation with the refined structure to check
if there is one and only one negative frequecy value.
4. Do IRC(=1 and -1) calculation to check if the refined
TS gives the reactants and product.
My result is that until step 3, everything seems OK. Refinning
the TS by NLLSQ/SIGMA/TS gives no significant change of the TS
that obtained from step 1, probably because I used the key word
PRECISE in step 1. The FORCE calculation showed that the refined
structure contains only one frequency values.
My problem is in the last step. When I do the IRC calculation
and try to look at the result structure with "molden" software,
it gives exactly same as the structure of TS I input.
I wonder if (i) my TS is not correct, or (ii) the IRC calculation
doesn't give the molecular structure result from the calculation
so that molden only edit the structure I input. In the latter
case, however, I don't know how to edit the molecluar structure
generated by IRC calculation.
Could anyone PLEASE help me how to confirm my TS structure by IRC?
I enclosed the input/result file at the end of this message.
Thank you very much in advance.
Sincerely,
Park, TAE-YUN

Dear TAE-YUN Park,
Concerning the IRC calculation, try the same calculation with keywords
LARGE and X-PRIO, so that the coordinates of the intermediate steps along the
reaction coordinate are written to the output file. Then have a look with
molden.

I don't know what molden is looking for, but the geometries generated during the
IRC may not be being kept. First, check the .out file to see whether
intermediate geometries from the IRC run are being preserved. If they are, then
the problem is probably with molden being able to read the file properly. If no
intermediate geometries are present, use some variation on the keyword LARGE to
get the coordinates written to the .out file. Check the documentation for your
version of Mopac; LARGE has changed meanings over the years, and means different
things in different contexts.

Hello,
I've never used MOLDEN for any purpose, I guess it reads only
the first structure from your output, always giving the initial
TS geometry.
As you may know, an output from IRC calculation contains more
than one geometry, i.e., geometries on the reaction coordinate
from the TS leading to either the reactants or the product.
Therefore, if a MOPAC job has been terminated normally,
the last structure in the ouput should correspond to the reactants
or the product.
Cut the final Z-matrix (or the Cartesian coordinates) from the output
and view it with a common molecule viewer program.
Good luck!

Dear Dr. Park,
I believe that you will find it very difficult to get transition states
for the electrophilic additions that you are interested in. There are two
problems here:
1) the reactions are usually very exothermic
and
2) a transition state probably does not exist in the gas phase
I have done a few AM1 calculations that illustrate each point (I used
SPARTAN version 4.1). First, I examined the addition of 2-propyl cation,
Me2CH, to propene, H2C=CHMe, to give 4-methyl-2-pentyl cation, Me2CHCH2CHMe.
This reaction converts a secondary cation into another secondary cation and
might be expected to be thermoneutral. It is not. The reaction is very
exothermic. The AM1 reaction energy is about -28 kcal/mol for
propene (7) + 2-propyl cation (192) -> product cation (171)
(AM1 heats of formation given in parentheses). An exothermic reaction is
actually expected in this case partly because a weak CC pi bond is replaced by
a strong CC sigma bond.
Next, I tried to find a transition state for the addition. I
constrained the length of the forming CC bond in the product cation to be 1.85
angstroms and optimized the geometry of the constrained product. The resulting
molecule had an AM1 energy of 182.5 kcal/mol and one large imaginary
vibrational frequency corresponding to stretching of the forming CC bond. In
other words, the structure and vibration data make this look like a possible
transition state.
Unfortunately, the energy of this molecule (182) lies in between the
energies of the reactants (199) and product (171). It does not correspond to
an energy maximum. Thus, when I tried to use this molecule and its Hessian to
find an AM1 transition state I was unsuccessful. The energy of the molecule
steadily climbed towards 199 and the molecule dissociated into propene and
2-propyl cation.
If you think about this type of reaction from a theoretical point of
view, say using the curve-crossing model of Shaik and Pross, it seems to me
that you would also predict that a transition state might not exist in the gas
phase. So these results could be fairly general.

Try to add the keyword LARGE, to your IRC input file. This produces the printing
of the intermediate structures along the IRC path, so you can monitor if the
geometry is changing from the TS to the reactants or products. You can even
create an animation of the reaction with the appropriate software, for instance
chem3D or Ball&Stick. One word of caution, as the name of the keyword indicates,
this can lead to really LARGE output files. You can control the amount of
printing by using LARGE=n. See the MOPAC manual for details!
I hope this helps you.

I have tried the calculation using MOPAC93 and it works perfectly. I used my
program Re_View to visualize both the negative frequency vibration of the T.S.
and the final reaction profile (which was automatically generated from the MOPAC
outputs using another of my programs IRC_CONV).
Here is a cut down version of the final reaction. Its in XYZ format so use
Re_View to view and analyze it.

Tae-Yun,
I am also using molden to visualise IRC outputs and I think you
are missing a point on how to use the program.
When Molden reads an IRC file it displays the first structure it
comes across in the .out file which will be the structure you
inputted. If you then want to see the structures resulting from the
calculation you use the movie button to run through them all at once,
the next button to move through them one at a time, or the Geom.
Convergance button to view the P.E. surface stepped along during the
IRC and select the structures of interest. These structure will be
different to the starting structure if the steps taken along the
reaction coordinate are large enough or there are many steps.
The Geom. Convergance screen is helpful in checking that your TS does
infact connect the products/reactants.If you then want to save a single
structure you can view it using one of the methods above and use the
Z-matrix facility to write the Z-matrix being viewed to a separate file.
I hope that I have been of some help.

(Concluding remarks for part V)
Concerning my question in part V, the problem was solved by the following
steps:
1. Use LARGE keyword to get the intermediate structure.
2. Get the final Z-mat structure in the *.out file.
3. Edit the final Z-mat with any graphical viewer.
