Asymmetrichyphen;Top Vibrationmdash;Rotation Hamiltonians

摘要

From the general molecular vibrationmdash;rotation Hamiltonian in the Nielsenmdash;Amatmdash;Goldsmith formulation, Hamiltonians for asymmetrichyphen;top molecules of the orthorhombic, monoclinic, and triclinic point group symmetries are deduced. These Hamiltonians are appropriate for the calculation of vibrationmdash;rotation energies to the fourth order of approximation.
