The absorption spectrum of NO, at room temperature, was recorded in the 5400-11000 cm(-1) region at resolutions ranging from 0.008 cm(-1) near 5400 to 0.023 cm(-1) near 11000 cm(-1) using a Bruker IFS120HR Fourier transform spectrometer. Sample pressure/absorption path length products ranging from 200 to 4700 mbar x in were used. More than 6000 absolute line intensities have been measured in 64 different bands of (N2O)-N-14-O-16. Using wavefunctions previously determined from a global fit of an effective Hamiltonian to more than 18000 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.
