Abstract
Spectra of the 5.3-μ band of NO have been obtained using a double-beam prism spectrometer. The total absorptance of the band was determined for NO concentrations of 0.004-atm cm to 5.4-atm cm pressure broadened by N2 up to 2100 mm Hg. Three cells were used with lengths of 1.55 cm, 2.54 cm, and 6.35 cm. The average broadening coefficient of NO relative to N2 was determined to be 1.00 ± 0.05. The band intensity was estimated to be 115 atm−1cm−2 STP ± 10%.
