Re: MEP (mininum energy paths) calculations

Alex Granovsky

Dear Antonio,

It is possible to do, you need to use runtyp=irc. See Firefly's
documentation on this runtyp for more details. I have attached
a sample input file below.

To compute IRC for excited states, use input files similar to that
for the excited state geometry optimization. You merely need to
introduce changes as appropriate for runtyp=irc and, in most situation,
you need to precompute hessian and provide it in the input file for
IRC procedure.

Kind regards,
Alex Granovsky
