WebOct 15, 2015 · Fixing the bond angle to a set value seems like an extreme solution to this problem. It is. To be honest, fixing parameters in a calculation is almost always no solution at all. The resulting geometry has little to no meaning and all derived properties are for a purely hypothetical case. WebThis module complements the capabilities of the more traditional Gaussian function based approaches by having an accuracy at least as good for many applications, yet is still fast enough to treat systems containing hundreds of atoms.

WebJul 5, 2005 · Hello all, I am currently trying out the BOMD routine in Gaussian03 on some radical structures. Presumably (i hope), this routine allows an insight in the dynamics of a radical at different temperatures. However, I would like to introduce some constraints (e.g. fixed bond angles).
