Dear Colleague,
On behalf of the MESMER team, we are delighted to announce that MESMER
6.1 (Master Equation Solver for Multi Energy-well Reactions) is now
available for download.
MESMER is designed to analyze and simulate reactions in the gas phase
that take place on a potential energy surface that is characterized by
having one or more potential wells, and which are typically described by
rate coefficients that depend on pressure (or concentration) as well as
temperature. MESMER allows you to simulate systems over a wide range of
pressures and temperatures, extract rate coefficients, analyze
experimental data, fit model parameters and represent rate coefficients
in formats that can be used directly in large scale simulations (e.g.
Cantera or Chemkin).
The Windows installer and Linux tar file are located at:
http://sourceforge.net/projects/mesmer/
The source can also be viewed and downloaded from this site. There are
also bug and feature request tracking facilities which we encourage you
to use.
MESMER 6.1 is largely a maintenance release, but includes the following
new features:
Biexponential down energy transfer model.
Lennard-Jones parameter calculation for compounds investigated by
Jasper.
Extension of definition of diffusive loss in trace fitting. We
thank Timo Pekkanen of the University of Helsinki, for suggesting this
change.
MESMER Input, bug fixes and Other Changes:
QD libraries used to provided extended precision have been
upgraded to version 2.3.22. Note this update will require a change to
build scripts as the QD library is generated in a sub directory. See
manual for details.
Deprecated keywords. Some keywords are to be retired and these
are listed in the manual.
An issue with reading the reference temperature used in the ILT
method has been addressed.
We thank Timo Pekkanen and Prasenjit Seal of the University of Helsinki
for bringing the following issues to our attention:
An issue with extended ILT has been addressed.
An issue with derived Arrhenius parameters has been addressed,
e.g., a given pre-exponential factor can now be derived from another pre-
exponential factor.
An issue with the weighted trace fitting for an equilibrating
system with diffusive loss terms has been addressed.
An issue with reactions with multiple transition states has been
addressed.
If you have any comments or suggestions, please do not hesitate to let us
know, either through the above site or by email (Mark
Blitz(M.Blitz-.-leeds.ac.uk) and Struan Robertson
(struanhrobertson-.-gmail.com) would be very happy to receive feedback).
More information is available at the MESMER website:
http://www.chem.leeds.ac.uk/mesmer.html
Also some of the implementation details of MESMER are described in
Journal of Physical Chemistry A, 95459560, 116 (2012).
A web based graphical user interface for creating MESMER input files,
developed by Dr. Xiaoqing You and colleagues of the University of
Tsinghua, in collaboration with the MESMER team, is available for testing
and can be found at the following address:

Dr. You and the MESMER team would welcome feedback on this interface.
Regards,
Mark Blitz and Struan Robertson
