Abstract:

The absorption spectrum of N2O in the region 9100-9500 cm-1 was studied using a highly sensitive intracavity laser spectrometer based on a neodymium glass laser. The threshold sensitivity and spectral resolution of the spectrometer are 10-8 cm-1 and 0.08 cm-1, respectively. Two vibrational-rotational bands centered at 9219 and 9295 cm-1 were recorded; these bands are formed by transitions to the Fermi-resonance polyad 4002. The spectroscopic constants of the high vibrational-rotational states of nitrous oxide were determined.
