## 摘要

The high-resolution FTIR spectra of the ν_{5} band of monoisotopic D_{3}^{70}GeH have been fitted by two sets of parameters corresponding to different reductions of the effective rotational Hamiltonian for the doubly degenerate vibrational state of a molecule of C_{3ν} symmetry. The unitary equivalence of both sets of parameters has been verified by using relations which follow from the theory of the reduction of the effective rotational Hamiltonians of C_{3ν} molecules. This made it possible to determine “true” values of the parameters of the Δl = ±2, Δk = ∓1 and Δl = 0, Δk = ±3 interactions, as well as of the higher-order terms η_{J} and η_{K} in the z-Coriolis coupling. Relations between unitary equivalent sets of spectroscopical parameters are compared for the ν_{10}) = 1 vibrational state of CF_{3}CCH, ν_{6} = 1 of CDF_{3}, and ν_{5}) = 1 of D_{3}^{70}GeH.
