The near-IR spectrum of polyethylene, polyethylene glycol, and polyvinylethyl ether have been measured. The CH and OH stretch and bend absorptions have been assigned using local mode theory. The CH stretch anharmonicities are about 57 cm−1, typical of CH anharmonicities in molecular sampl...
Infrared (IR) spectroscopy is the established technique for identifying polymer materials and has been used extensively for identifying large (over 100 micrometer) polymer materials. The Spectrum Two ™ is a portable FT -IR spectrometer that can operate from a battery pack and has been used on ...

IR spectrum of MFTIR - fibrous material - polyethylene terephthalate - triacetateWe investigated the influence exerted by the conditions of preparation of specimens of fibrous materials made of polyethylene terephthalate and triacetate threads and fabrics and the conditions of recording IR spectra of ...
Nitrile rubber (NBR) is a common analysis object in the field of non-metallic failure analysis. Usually, the sample state greatly affects the quality of the spectrum when collecting its infrared spectrum (IR), leading to increased difficulty in interpretation. This paper took NBR as an example ...
