Abstract

The frequencies, wavelengths, and line strengths for transitions of the CH molecule at microwave and far-infrared wavelengths have been calculated from an analysis of the laser magnetic resonance spectrum. The low-frequency transitions are between lambda-type doubles, while the higher frequency transitions are between different spin-rotation levels.
