Infrared spectra and intensities of the H2O and N-2 complexes in the range of the v(1)- and v(3)-bands of water

The IR spectra of complexes of water with nitrogen molecules in the range of the symmetric (nu(1)) and antisymmetric (nu(3)) bands of H2O have been studied in helium droplets. The infrared intensities of the nu(3) and nu(1) modes of H2O were found to be larger by factors of 1.3 and 2, respectively, in the N-2-H2O complexes. These factors are smaller than those obtained in recent theoretical calculations. The conformation of the N-2-H2O complex was estimated. Spectra and IR intensities of the (N-2)(2)-H2O and N-2-(H2O)(2) complexes were also obtained and their structures are discussed.
