摘要：
In this paper we attempt to reproduce quantitatively the IR spectra of 2-mercaptoquinoline in the nu(N-H) and nu(N-D) band frequency regions. The investigated spectra were quantitatively interpreted within the limits of the ''strong-coupling'' theory for the hydrogen bond vibrations in centrosymmetric H-bonded dimers, including the observed isotopic effect. The observed, very nonregular, spectral properties of 2-mercaptoquinoline were found to be connected with the ''strong-coupling'' mechanism as well as with the electronic properties of the H-bonds in the molecular associates.
