The application of Fourier transform Raman spectroscopy to the identification and characterization of polyamides—I. Single number nylons

Abstract High quality Fourier transform Raman spectra, substantially free from fluorescent background, have been obtained for twelve double-number nylons ranging from nylon 1,3 to nylon 10,10. These spectra, obtainable on a routine basis, prove to be highly characteristic and therefore of considerable value for analytical purposes. The characteristic trends observed in some regions of this series of spectra are investigated and discussed. A less detailed study suggests that Fourier transform Raman spectroscopy should also be of value for the characterisations of nylon co-polymers.
