The high resolution excitation laser spectrum of the C 2A1-- X 2A1 transition of CaNH2 was recorded with a laser ablation/supersonic molecular beam source. The molecule was made by ablating Ca metal with the second harmonic of a pulsed Nd:YAG laser followed by reaction of with 5% NH3 seeded in Ar(or He). Laser induced fluorescence spectra was recorded 12 cm downstream from the nozzle with a single-mode cw ring dye laser. Molecular constants for the Ka ' = 0---Ka '' = 0 sub-band have been determined. The Ka ' = 1 ---Ka '' = 1 sub-band is currently being analysed.
