The exact quantum mechanical kinetic energy operator in internal coordinates for vibration of a hexatomic molecule

摘要

The full nonrelativistic quantum mechanical vibrational J=0 kinetic energy operator for a hexatomic molecule, (A,B)-C-D-(E,F), expressed in valence stretch, bend, and torsion internal coordinates is given explicitly. The derivation of the operator is reviewed and some of its properties and possible applications discussed. (C) 1998 American Institute of Physics. [References: 18]
