TIME RESOLVED ICLAS SPECTROSCOPY of $HO_{2}$ RADICAL

Author Institution: Department of kinetics and katalysis, N.N. Semenov Institute of Chemical Physics; Levedev Physical Institute, N.N. Semenov Institute of Chemical Physics$HO_{2}$ radical absorption spectrum was recorded in the 1.22-1.27 mkm range with the spectral resolution $0.13 cm^{-1}$ using intracavity laser absorption spectrometer based on $F^{+}_{2}$ color centers LiF laser. The rotationnaly resolved vibronic bands: (0,0,0)-(0,0,0), (0,2,0)-(0,1,0) and (0,0,2)-(0,0,1) of the $A^{\prime} - A^{\prime\prime}$ electronic transition were analyzed. The mechanism of the forbiden rotational subbands appearance will be discussed
