摘要：

The vibrational spectra of jet-cooled aniline-benzene and aniline-cyclohexane clusters have been investigated using infrared depletion spectroscopy combined with REMPI-TOF mass spectrometry. The symmetric and antisymmetric NH2 stretching bands are red-shifted by 28.4 and 40.9 cm(-1) in aniline-benzene and by 1.6 and 1.2 cm(-1) in aniline-cyclohexane, from those of the aniline monomer. The spectrum of aniline-benzene suggests a face-to-face structure with NH2-pi hydrogen bonds. This structure is supported by ab initio calculations at the MP2 level, which also reproduce the observed red-shifts. The small red-shifts in aniline-cyclohexane indicate no direct interaction of the amino hydrogens with cyclohexane. (C) 1998 Elsevier Science B.V.
