Abstract

The spectrum of nitrous oxide has been measured with a high-resolution grating spectrometer in the region from 2395 to 3510 cm⁻¹. Long absorbing paths were used in a heated cell, so that it was possible to observe many of the weaker bands, including those with lower vibrational levels ν₂, 2ν₂⁰, 2ν₂², and ν₁. Accurate values of the rotational constants have been obtained, including the l-type doubling and variations with v and l of the centrifugal stretching constant. These have been correlated with other data to obtain improved values of the molecular constants, with particular attention to the Fermi interaction. Other weak interactions are observed and discussed.
