 Title: HIGH RESOLUTION STUDIES OF THE $A^{1}\P - X^{1}\Sigma^{+}$ BAND SYSTEM OF GeO Creators: Żyrnicki, W. Issue Date: 1980 Abstract: The 0-1, 0-2 and 2-3 bands of the $A^{1}\P - X^{1}\Sigma^{+}$ system of germanium monoxide have been recorded at high resolution and analyzed. The rotational constants obtained for the ground state agree well with microwave date and those for the excited state are an improvement of the previous results. On the basis of investigations of intensity distribution in the GeO spectrum a perturbation between the $b^{3}\P(v-=8)$ and $A^{1}\P (v=0)$ states was $concluded.^{1}$ In the present study of the rotational structure of the 0-1 and 0-2 bands the points of maximum perturbation have been observed for $^{74}$GeO at Q(37) - G(39), P(41) and R(39). The perturbation of the $A^{1}\P$ state is discussed. URI: http://hdl.handle.net/1811/11204 Other Identifiers: 1980-MF-4
