摘要：

Vibrational modes in the N-H stretching region have been assigned to each submolecule in (NH3)2 on the basis of comparison of infrared and Raman spectra and the spectra of (NH3)(N(CH3)3) dimers. The submolecules are clearly different with one perturbed more strongly than the other and one exhibiting stronger Fermi resonance interaction between its internal v1 and 2v4 modes. The small vibrational perturbations show that the interaction is weaker than that normally associated with classical hydrogen bonding.
