The fluorescence spectrum induced in ClO 2 by excitation with the 4765 Å argon-ion laser line has been studied under moderate resolution with the laser in single mode operation and under high resolution with the laser in multimode operation. The most intense features of the fluorescence have been assigned to excitation by the 23 2, 22 ← 24 2, 23 transition of the (0, 0, 0) ← (0, 0, 0) band of 37ClO 2. Another set of features has been assigned to excitation by the 38 0, 38 ← 37 0, 37 transition of the (0, 0, 0) ← (0, 0, 0) band of 37ClO 2. The vibrational structure and the ν 1 vibrational dependence of the rotational structure in the fluorescence have been least squares fitted giving a new set of vibrational constants and vibration-rotation interaction constants, α 1 B and α 1 C .
