Abstract The absorption spectrum of N 2 O, at room temperature, was recorded in the 5400–11 000 cm –1 region at resolutions ranging from 0.008 cm –1 near 5400 to 0.023 cm –1 near 11 000 cm –1 using a Bruker IFS120HR Fourier transform spectrometer. Sample pressure/absorption path length products ranging from 200 to 4700 mbar×m were used. More than 6000 absolute line intensities have been measured in 64 different bands of 14 N 2 16 O. Using wavefunctions previously determined from a global fit of an effective Hamiltonian to more than 18 000 line positions [Tashkun SA, Perevalov VI, and Teffo JL, to be published], the experimental intensities measured in this work and by Toth [J Mol Spectrosc 1999;197:158–87] were fit using 62 parameters of a corresponding effective dipole moment, with residuals very close to the experimental uncertainty.
