Geometry optimization along IRC

Dear Tian,

Is geometry optimization performed at any point along IRC calculation? In other words, is the structure found for ith point along IRC profile partly/fully optimized?

Sincerely,
Saeed

Re: Geometry optimization along IRC

No. The geometries generated in IRC task is not optimized. There are many IRC algorithms, see article titled "Finding minima, transition states, and following reaction pathways on ab initio potential energy surfaces" for review.
