Abstract
The infrared spectrum of solid nitrous oxide has been obtained at 80°K. Several bands due to isotopic species are seen. In contrast with CO2, no evidence is observed for splitting due to intermolecular coupling or for reflection peaks in the spectrum. Spectral features assigned to torsional lattice motions (with fundamentals at 80 and 91 cm—1) and to translational lattice motions (as broadening of v3) are present.
