CCL:G: IRC & TS CALCULATION



 Sent to CCL by: "tarig elshaarani mohamed" [shaarany_11|,|yahoo.com]
 Dear Sir/Mme:
    I am a gradute student from  Sudan ,working on theoretical studies
 of
 Diels_Alder reaction using G03,(following the reaction using density
 function theory)..my problem is that; whenever i make my (input)file by
 Molder and (export )it to G03 to process calculations,especially when i
 use IRC or TS as keywords a message pop up to me reading(insert the
 force constant calculations) but when i respond to this by writing(calc
  FC ) as key word with IRC or TS, another message pop up reading (input
 error)..What do you suggest i should do to overcome this?...Also is
 there any software that can prepare the coordinates as Z matrix?....
     Thank You so much
