First- and Second-Overtone Intensity Measurements for CO and NO

Abstract
The intensities for the first and second overtones of CO and NO have been measured using the Wilson—Wells—Penner—Weber self‐broadening technique. The reported values are A CO 2,0=2.15±0.10, A CO 3,0=0.0127±0.0013, ANO 2,0=2.11±0.10, and A NO 3,0=0.0458±0.0046 in units of cm−1/cm·atm at 273°K. The results have been interpreted using an anharmonic‐oscillator model to obtain alternate sets of dipole‐moment coefficients.
