Double resonance study of relaxation in nitric oxide

Abstract

A double resonance technique, employing a pulsed transverse HF laser to pump the ν =0→2 level of the ²Π_1/2 ground electronic state of NO and a CW electrically excited CO laser to probe the ν =1→2 and ν =2→3 levels of both the ²Π_1/2 and ²Π_3/2 states of NO, was used to determine the V‐T rate constant k₁₀ and estimate the V‐V and spin relaxation rates. The value of k₁₀ for the process NO(1)+NO(0)→2NO(0) was found to be 2.6±0.2×10³ torr⁻¹ · sec⁻¹ at 295°K.
