Abstract

The high-resolution absorption spectrum of the Q branch of the ν₂ band of the ⁷⁴GeH₄ molecule has been recorded. The accuracy of determination the line centers was 2 × 10^-3-5 × 10^-4 cm^-1. The spectrum obtained has been interpreted. By simultaneously analyzing the states (0100, E) and (0001, F₂) spectroscopic constants have been determined for these two states, as well as resonance constants of the type of X_EF₂ ^Ω(K,Γ). The parameter values obtained reproduce the spectrum with an accuracy close to the experimental one.
