Some applications of the virial theorem to molecular force fields: The zero virial reaction coordinate and diatomic potentials from the normalized kinetic field functions
Abstract:For a fixed-angle potential energy surface (PES), W(Q), following the zero virial path (ZVP), on which 2," Q, -V,W(Q) = 0, provides an efficient way for locating the transition state and generating a g o d approximation to the minimum-energy reaction path; vector Q = (Q1, . . . , QN) stands for nuclear coordinates. An algorithm which employs the ZVP following is proposed for exploring PESS when starting from the reactant (or product) region. It seems that this approach allows one to avoid some discontinuities … Show more
