✦ Synopsis

The absolute infrared infensities of the O-I, O-2 and 1-2 vibration-rotation bands in the ' Z'gound state have been calculated from fust principles. The dipole moment function for NO+wns determined in the region of the equilibrium internuclmr separation by an accurate multi-configuration self-consistent-field procedure.

The dipole matrix elements over vibration states were solved exactly using numerical techniques.

The ratio of the calculated integated absorption coefficients for the fundamental and first overtone (88.8 cm-* atm-' and 0.6 cm-* atm-', respectively, at 273.16'K) is in reasonable agreement with an estimate based on observation of these bands in NO+ at high a!titudes in the upper atmosphere.
