✦ Synopsis

Eight emission spectra of pure N 2 O and N 2 O + N 2 + He mixtures excited by a radio frequency discharge were recorded by Fourier Transform Spectroscopy at a resolution of 0.005 and 0.004 cm À1 in the 4.5 lm region. Results (wavenumbers, band centers, and spectroscopic constants) concerning nine new vibrational transitions which have not been observed before, and which occur between highly excited levels of the bending mode are reported. The derived spectroscopic parameters allow us to reproduce the experimental wavenumbers with an RMS error lower than 4.5 Â 10 À4 cm À1 .

The experimental technique which consists of exciting a mixture of N 2 O and N 2 by radio frequency is very efficient for populating very high vibrational levels. Twelve emission spectra of mixtures of N 2 O and N 2 were recorded with a Fourier transform spectrometer at resolutions of 0.006, 0.004,
