✦ Synopsis

A simple technique for estimating the slit width of a spectrometer from the ratio of the observed and (Dm 1ΒΏ2

) R of a Raman line proÐle was developed by calculating a set of corresponding values of (Dm 1¿4

) R and based on the exact numerical evaluation of the Voigt proÐle. This

) R technique was applied to some selected Raman lines and was found to give accurate values of the slit width in almost all cases where the slit distortion is appreciable and the band is isolated. Another technique for calculating the fractional Lorentzian character from the observed Raman spectra is also suggested.

A simple method to determine polymer blend compositions from their Raman spectra is presented. The method is based on expanding linearly the experimentally measured Raman spectrum of the blend, in terms of Raman spectra of pure components. A smooth function has also been included in the linear expan
