✦ Synopsis
A dispersive fiber-optic Raman spectrometer was used to remotely monitor, in real-time, the local temperature and t h e extent of reaction of a commercial cyanate ester polymer (AroCy L-10). T h e local temperature was determined by solving the Boltzmann relation governing the intensity ratio of the Raman Stokes and anti-Stokes scattering of a reference mode which does not vary with the reaction chemistry. T h e extent of the reaction can be monitored using either individual peaks associated with the reactant or product or by using the entire spectrum and principal component multivariate calibration. T h e use of principal component analysis has distinct advantages over the single-peak method.
