Rotational analysis of the ultra-violet bands of germanium monoxide

Abstract

From measurements on high-dispersion spectrograms, rotational structure analysis is made of the (1, 0), (2, 0) and (0, 3) bands of the ultra-violet band system of germanium monoxide (GeO). The bands are found to be due to a 1Σ → 1Σ transition and are thus analogous to the A bands of SnO and PbO, as has been suggested in a previous communication. Relevant molecular constants have been obtained for both the states. A few lines due to the less abundant isotopic molecules 70GeO and 72GeO have been observed in the (0, 3) band.
