Abstract
Asymmetric line shapes in the BA system of the deutroxyl radical have been observed. For the P220, P120, P220, and P121 transitions of the (0, 9) band, the resonance widths are, in cm1, 0.4 ± 0.2, 1.1 ± 0.2, 0.4 ± 0.2, and 0.2 ± 0.1, respectively, and the line profile indices are +2.5 ± 0.5, -2.0 ± 0.5, -3.0 ± 0.5, and +5.0 ± 1.0, respectively.
