Strongly Bonded Bimolecular Complexes between HCN and HNC

Autor: and Antti Heikkilä, Jan Lundell

Publikováno v: The Journal of Physical Chemistry A. 104:6637-6643

The equilibrium structures, vibrational properties, and interaction energies for four bimolecular complexes of HCN and HNC (HCN···HCN, HNC···HNC, HCN···HNC, and HNC···HCN) were studied with ab initio methods. Different electron correlatio
