摘要: Abstract The pseudo potential energy term U ( ρ ) obtained from the kinetic of Hougen-Bunker-Johns (HBJ) rotation-vibration Hamiltonian has been in general to order magnitude κ 2 T v . expression is relatively easy evaluate and should be used any semirigid bender or nonrigid that derived HBJ Hamiltonian.
