[CP2K:7721] Transition State Optimization with Dimer Method

[luca]

Hi Natalie,
tightening convergence criteria you should observe a commensurate 
conformational change, thus, I do not aspect huge changes otherwise, the
system is not really converged.
Anyway, it is system dependent. To fully characterize the TS (or more
TSs for multiple path reaction) you should perform other TS searches,
for example, starting from different conformation of the system. You can
refine the characterized TS re-doing the TS  search starting from the
last TS geometry obtained, but using a new randomized dimer directions
set.

good luck,

Luca
