Because of the recent progress in near-infrared Fourier transform (n.i.r.-FT) Raman spectroscopy, it has become possible to circumvent the fluorescence problem which precludes recording Raman spectra of many important systems, such as some polymers widely used in industry. Being especially concerned with polyacrylonitrile (PAN), we have carried out preliminary ab initio SCF calculations in order to...
