The (000)-(000), (010)-(000), and (020)-(000) bands of the A-approximately-1 A"-X-approximately 1A' transition of the HGeCl molecule were observed by laser induced fluorescence spectroscopy. The K-subband heads were resolved, and the transition wavenumbers of these heads were measured with a resolution of 0.04 cm-1. The molecular constants of the relevant vibronic levels were determined by a least-squares analysis of the observed wavenumbers.
