The 18 373 cm-1 band in the fluorescence excitation spectrum of jet-cooled CrO2F2 has been recorded with 0.007 cm-1 linewidth. The stronger lines have been assigned to a type c transition, consistent with a B1←A1 vibronic transition analogous to that in CrO2Cl2. Ground-state rotational constants, A″=0.148, B″=0.130, and C″=0.120 cm-1, agree well with electron diffraction predictions. The B1 excited state is significantly perturbed. Evidence includes (i) a decreasing fluorescence yield with increasing J′, such that signals were not observed for J′>3, (ii) the appearance of ‘‘extra’’ lines in the spectrum, leading to perturbing levels strongly mixed with levels of the B1 state, and (iii) anomalous effective rotational constants for the B1 state.
