摘要: Abstract The absorption spectrum of nitrous oxide (N 2 O) has been recorded by Intracavity Laser Absorption Spectroscopy between 12,760 and 12,900 cm −1 . rotational analysis led to an improved determination rovibrational parameters the 6ν 3 +ν –ν bands 14 N 16 O. high J levels (0 0  0 6) (0 1  1 upper states were found perturbed anharmonic interaction. Line intensity values band are provided main effective dipole moment parameter determined.
