Yes, there’s definitely a need to track a variety of properties through multiple steps. We’re getting into some transition state / reaction path calculations, and tracking the vibrational modes through the IRC / NEB is very helpful. (This would also be a good teaching exercise.)
I have some ideas on this and I’m penciling in early summer for “more properties across steps” work (e.g. bond lengths / geometry, forces, orbitals, etc.)
And hopefully the NSF proposal we submitted back in December comes through because it’s very much along these lines.
