Vibrational Analysis of the TS: Difference between revisions

Revision as of 06:46, 28 February 2017

Description: the Improved Dimer Method needs an educated guess of the decay path, which is extimated from the hardest vibration mode with imaginary frequency of the TS geometry (which is a planar NH3 molecule):
