Hello there noble science people...

i am doing equilibrium geometries and saddle point searchs in gaseous phases. but the experiments in which the mechanism were based, used polar solvent and the substances involved were charged particles (although closed shell species).

does this mean i have to emulate these solvent effects for better elucidation and results ? or it'll just make calculation more expensive with little positive gain.

if so,,, is the PCM compatible with geometry and sadsearch? or is there any other alternative approach?

Thank you all. Live long and prosper.
