Using a harmonic general valence force field previously determined for NX3, PX3, AsX3 and SbX3 (X is H, D, T), the harmonic wavenumbers and normal coordinates have been calculated for pyramidal molecules of the type XYZ2 (Y is N, P, As, Sb; X, Z are H, D, T). For the nitrogen molecules, harmonic wavenumbers also were obtained for the nitrogen-15 isotope and hypothetical molecules in which X and Z take on masses of 6, 20, and 1000 amu. The wavenumbers for the nitrogen molecules, XNH2, XND2, and XNT2 over the range X=1–1000 amu, and HNZ2, DNZ2, and TNZ2 over the range Z=1–1000 amu are plotted.
