Spectrum of water vapor between 8050 and 9370 cm −1

Abstract

Measurements of the line positions of H 2 16O in the 8050 to 9370 cm −1 region have been performed at a spectral resolution of 0.07 cm −1. A grating spectrum of room-temperature water vapor and a Fourier transform spectrum of heated water vapor (T ⋍ 60°C) were used in the interpretation. A careful analysis of the bands ν 1 + 3 ν 2, 3 ν 2 + ν 3, 2 ν 1 + ν 2, ν 1 + ν 2 + ν 3, and ν 2 + 2 ν 3 has led to a set of rotational levels belonging to the vibrational states (130), (031), (210), (111), and (012). Many vibrorotational resonances were detected.
