✦ Synopsis

The laser-induced fluorescence spectrum of gas-phase PHI cooled in a supersonic jet has been observed in the range 490-550 nm. A rotational analysis was carried out for the (0, 0, 0)-(0, 0, 0), (0, 1, 0)-(0, 0,O) and (0,2,0)-(O, O, 0) bands of the A 'A,-X ZBI electronic transition of PHr. About 220 lines have been assigned, including 52 lines for the first time. From the rotational structure of the spectrum, we obtained all molecular constants of PH2 including ebb and E, which are the first reported. A discussion of the rotational perturbation which exits in the electronically excited state is presented.
