Investigation of Polyester Structure by Laser Raman Spectroscopy
The fact that Raman spectroscopy has experienced a rebirth through the advent of the laser, the improvement of double-monochromator design, and the application of photon counting techniques has now been well established. The field of polymer chemistry has already been influenced by this new instrumental capability. For example, one can now gain useful structural information about molecular systems which, prior to the present state of the art, could not even be considered. One such molecular system is that of polyesters, and this paper deals with the application of laser Raman spectroscopy to the investigation of polyester structure.
