``Monomethyl Gallium: Prelude to Spectroscopy,'' B. C. Hoffman, C. D. Sherrill, and H. F. Schaefer, J. Mol. Struct. (Theochem) 370, 93-95 (1996).

The AlCH3 molecule has been observed by both neutralization-reionization mass spectrometry (NRMS) and resonance-enhanced multiphoton spectroscopy (REMPI), and GaCH3 is a target molecule for both experimental techniques. Ab initio quantum mechanical methods have accordingly been applied to GaCH3. GaCH3 is predicted to have a C3v equilibrium geometry, and theoretical values of its rotational constants, vibrational frequencies and infrared intensities are presented.
