Abstract
The ammonia "inversion" lines near 1.25-cm wave-length are resolved, their widths being decreased at low pressures to 200 kilocycles. Line shapes, intensities, and frequencies are measured and correlated with theory. Calculated intensities and Lorentz-type broadening theory fit experimental results if frequency of collision is fifteen times greater than that measured by viscosity methods. Splitting due to rotation is in fair agreement with a recalculation of theoretical values. A saturation effect is observed with increase of power absorbed per molecule and an interpretation made.
