Analysis of (1, 2) (1, 3) and (2, 3) Bands in the c3IIu-b3IIg System of P2
Chin. Phys. Lett. 2007, 24 (1):
We investigate the high resolution absorption spectroscopy of P2 radical, generated in ac glow discharge of PCl3 buffered with helium, using optical heterodyne magnetic rotation enhanced concentration modulation spectroscopy in the visible region. The (1, 2), (1, 3) and (2, 3) bands of c3IIu-b3IIg in the range 16620--17860cm-1 are observed and their 3II2-3II2 subbands are rotationally analysed. A set of effective molecular constants for the Ω=2 component of the states involved are determined.
