✦ Synopsis

The infrared laser absorption spectrum of the PO 2 free radical has been detected in the reaction of oxygen atoms with white phosphorus. Over 300 lines of the u 3 fundamental band of the 2A 1 ground state have been measured and assigned between 1300 and 1345 cm-1. Rotational, centrifugal distortion and spin-rotation constants for the v 3 = 1 level have been obtained from fitting the lines to an asymmetric rotor Hamiltonian, with the ground state constants held at their microwave/laser magnetic resonance values. The band origin is 1327.
