The infrared spectrum of HNO

Abstract

Vibration–rotation spectra of HNO (DNO) have been observed in a flow system following the reaction of hydrogen (deuterium) atoms with NO. The spectra were recorded at approximately Doppler limited resolution with a large Fourier transform spectrometer. Complete analyses have been made of the ν1 bands of HNO and DNO with the following results (in cm−1).[Formula: see text]Spectra of ν2 (NO stretching) were also observed in both HNO and DNO, but ν3 (bending) proved too weak to be detected in either molecule.
