摘要：

Fourier transform spectra have been measured for the rotational (Δv = 0) and vibrational (Δv = 1) spectra of lithium hydride and lithium deuteride in the gas phase. Dunham potential constants and rovibrational constants are given for LiH and LiD. Difficulties were encountered in attempts to fit all four isotopic species to a single modified Dunham potential function. Even data for a single isotopic species could not be fit to a Dunham potential function without significant systematic deviations. These problems are attributed to breakdown in the Born-Oppenheimer approximation. © 1990.
