摘要: Abstract Although curve fitting provides a method for obtaining intensity data the individual components of overlapping band systems, number configurational and conformational bands in C-Cl stretching region vibrational spectrum poly(vinyl chloride) is such that many parameters have to be optimized. It therefore desirable impose constraints calculations, prior knowledge component would valuable. The potential derivative spectroscopy this information has been examined. shown superior resolution second fourth spectra partially offset by their inferior signal-to-noise ratio, discriminatory effect against broader bands, interference subsidiary peaks. used examine CH2 deformation modes three PVC samples different tacticity. With former system proves more complex than hitherto realized; hence, t...
