NH2(X Bi) Frequencies of Fundamental, Overtone, and Combination Vibrations (Vi,V2,V3) (in cm ) for the Rotational Ground State 0q,o- 

From laser-induced fluorescence spectra [10]. - Value extrapolated because of the strong perturbation due to resonance between the states (0,9,0) and (0,3,2) for Kg = 0 [10]. -From electronic emission spectra [11]. - Extrapolated [10]. - From a rotational 

Ab initio-calculated vibrational frequencies are published for Vi 2, V2 6, and Va 2 [14]. Bending overtones (0,V2,0) (up to V2 = 22) were calculated by using empirical potential curves [15, 16] or ab initio procedures [17 to 19]. 

NDg and NHD Radicals. Experimental frequencies of the bending vibration were reported for gaseous ND2 and for NHD in a matrix. Stretching and bending vibrational frequencies of ND2 and NHD were derived from an ab initio-computed general valence force field of 4th order [22] which reproduces the experimental NH2 fundamentals to within a few cm . The frequencies of Vi, V2, 2v2, and V3 vibrations (in cm ) are compiled in the following table
