The intramolecular vibrations of the ammonia water complex. A matrix isolation study

Abstract
The infrared spectrum of the ammonia water complex has been recorded from 10 to 4000 cm−1 for complexes trapped in neon and krypton matrices. Spectra have been observed for NH3 or ND3 complexed with H2O, HDO, or D2O. The observed intramolecular fundamentals are compared with frequencies calculated from a rigid-molecule harmonic oscillator model.
