The absorption spectrum of N2O, at room temperature, was recorded in the 5400-11Â 000Â cm-1 region at resolutions ranging from 0.008Â cm-1 near 5400 to 0.023Â cm-1 near 11Â 000Â cm-1 using a Bruker IFS120HR Fourier transform spectrometer. Sample pressure/absorption path length products ranging from 200 to 4700Â mbarÃm were used. More than 6000 absolute line intensities have been measured in 64 different bands of 14N216O. Using wavefunctions previously determined from a global fit of an effective Hamiltonian to more than 18Â 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.
