In this book, measurements using vibrational spectroscopy techniques for both the chemical and physical characteristics of polymers are described, alongside chapters covering spectra-structure correlations and spectra calculation. Special chapters deal with composites and conducting polymers, while others discuss the role of vibrational spectroscopy in understanding polymer weathering and degradation, and determining the optical, dielectric and solar and thermal properties of polymers. Dichroism measurement methods, important in understanding product performance, are covered, as well as practical methods for determining molecular orientation; linear, biaxial and trichroic determinations for polymers, as are dynamic measurement systems.
