Vibrational analysis of polyethylene terephthalate and its deuterated derivatives

TLDR: In this article, the vibrational analysis of polyethylene terephthalate, polymethylene-d/sub 4/T/T4/4/T 4, polyethylenes-d-sub 4-T/t/T-4-T 4/4 t/T 2, polymethylenes-terephthalates-d−sub 4−4−T 4−T/4−4

Abstract: The vibrational analysis of polyethylene terephthalate, polyethylene-d/sub 4/ terephthalate, and polyethylene terephthalate-d/sub 4/ was carried out using a valence force field calculated from the infrared and Raman spectra of a series of low molecular weight aromatic esters. The Raman spectra for polyethylene-d/sub 4/ terephthalate and polyethylene terephthalate-d/sub 4/ are presented and band assignments for these compounds and polyethylene terephthalate are discussed.
