Abstract:

Infrared Fourier transform spectroscopy of the first overtone of the nitric oxide NO bond stretch in nitrosyl bromide ONBr has been performed at a resolution of 0.02cm-1 to obtain the rotational parameters of the V sub 1 2 energy level. Roughly 1000 transitions have been observed for rotational levels up to J 80 and K sub a 7. The calculation of the complete set of rotational energy levels of this asymmetric molecule requires the numerical diagonalization of four, tridiagonal matricies for each J. From a non-linear least squares fit of observed transitions with J or to 40 using an approximation for the energy levels, the maximum J value accurately approximated was determined to be twenty-four. The fit was reaccomplished for J or to 24. The Monte Carlo analysis suggests the need to use higher J levels to determine the distortion constants.
