Vibration-rotation spectrum of N2O in the region of the lowest fundamental ν2

Abstract The high resolution infrared spectrum of N 2 O in the region of ν 2 has been studied with a Fourier transform spectrometer at a resolution of (about) 0.005 cm −1 and an accuracy of about ±0.00005 cm −1 . In addition to ν 2 , “hot” bands associated with this band and the bending fundamental ν 2 of 15 N 14 N 16 O and 14 N 15 N 16 O were analyzed.
