Abstract

Hydroxyl radical molecular beam was generated by DC pulsed high voltage discharge. The rotational resolution excitation fluorescence spectra of the H A ²Σ⁺ - X²Π (1, 0) band were observed by using second harmonious output of a nanosecond dye laser (around 282 nm). The rotational temperature of the (1, 0) band was determined to be (30 ± 1) K based on the analysis of the intensity distribution of the H spectra. Moreover, the fluorescence decay curves of the (1, 1) band and the (0, 0) band and were obtained and the fluorescence lifetimes of A ²Σ⁺ (v'=1) state and the X ²Π (v″ = 0) state were fitted to be (637 ± 16) and (675 ± 13) ns, respectively.
