Description |
Raman study of CN-stretching mode of acrylonitrile and ring-breathing mode of 2Cl-phenol was made in the binary mixture of (acrylonitrile + 2Cl-phenol) at different molar ratios of the two components. Raman spectra were recorded in the different spectral regions, 990–1070 cm−1 and 2170–2300 cm−1. Ring-breathing mode of 2Cl-phenol exhibited two components, which were attributed to the neat and self-associated dimer of 2Cl-phenol molecules. The self-associated structure of the dimer was obtained by geometry optimization. Other structures, which were calculated, include self-associated structure of acrylonitrile and the hydrogen-bonded complex of (acrylonitrile + 2Cl-phenol). All the geometry optimizations were made using density functional theory (DFT) and B3LYP functional employing the 6–31 + G(d,p) basis set. The variations of the linewidth and the peak position with concentration are explained on the basis of a model, which includes both the effect of concentration fluctuation in a microscopic volume and the influence of concentration-dependent microviscosity based on a model proposed recently by our group
