The vibrational structure of the $5500\backslash AA$ band of XeO has been reported by $Cooperetal1$. In the present work the rotational structure of the 0--4, 1--5, and 0--5 vibronic transitions in the $5500\backslash AA$ band of XeO have been resolved. Spectra were taken of an air-xenon mixture at 0.24 torr using 3.5 Mc excitation. Less than 0.1% air was present. Preliminary analysis of the data gives the following rotational constants: $B\_\{o\}\{^\{\backslash prime\}\}1=0.09\; \backslash pm\; 0.02\; cm^\{-1\},\; B\_\{2\}\{^\{1\}\}=0.06\; \backslash pm\; 0.01\; cm^\{-1\},\; B\_\{4\}""\}=0.39\; \backslash pm\; 0.02\; cm^\{-1\},\; B\_\{5\}""\}=0.31\; \backslash pm\; 0.03\; cm^\{-1\}$.
