Abstract
Here we report the preliminary analysis of the high resolution spectra of (GeH4)-Ge-70 (6000) and (7000) stretch overtone bands obtained by intracavity laser absorption spectroscopy (ICLAS). The observed P(J+1) , Q(J), and R(J-1) transitions agree well with the combination differe nce relations, indicating that the Coriolis coupling in the degenerate states is negligible. This is an important feature for a spherical to p molecule near the local mode limit. The vibration-rotational energy levels of upper states as well as those of some perturber states are o btained. The improved local mode parameters of GeH4 are also derived.
