Summary
A spin labelled poly(decamethylene terephthalate) where the label is covalently bound into the aliphatic chain, has been studied by EPR spectroscopy. The motion of the label is strongly anisotropic at low temperatures, probably due to the extended all-trans conformation of the alkyl chain. The anisotropy of the label rotation decreases with increasing temperature. Two approaches to analyse the spectra at high temperatures are presented.
