A Raman spectroscopic method has been developed that allows the precise and rapid determination of the degree of sulphonation (DS) of sulphonated poly(aryl ether sulphone). The calibration samples were characterized extensively by several independent reference techniques. It was possible to identify
## Abstract A range of thermally annealed isotropic and uniaxially drawn PEEK films were examined using polarized Fourier transform Raman spectroscopy in an attempt to obtain useful quantitative correlations with crystallinity. Both univariate (carbonyl stretching wavenumber measurement) and multiv
