GLOBAL ANALYSIS OF 24 ROVIBRATIONAL BANDS OF THE OCTAD OF THE [sup.76]Ge[H.sub.4] MOLECULE

A global fitting method has been developed for spherical top molecules. The octad of the GeH4 molecule comprising 24 interacting states has been investigated. By solving the inverse spectroscopic problem, positions of the band centers and rotational and resonant parameters are calculated. A total of...

description A global fitting method has been developed for spherical top molecules. The octad of the GeH4 molecule comprising 24 interacting states has been investigated. By solving the inverse spectroscopic problem, positions of the band centers and rotational and resonant parameters are calculated. A total of 70 variable parameters allow 1184 initial experimental rovibrational energies to be reproduced with a standard deviation of 1.2 x [10.sup.-3] [cm.sup.-1]. Keywords: Germane molecule, global analysis, spectroscopic parameters.
