Abstract : 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, typical of CH anharmonicities in molecular samples. The CH bend anharmonicities are 7, 10 and 11 /cm, respectively, for polyethylene, polyethylene glycol and polyvinylethyl ether. The CH bend absorption intensities decrease by about a factor of 4 allowing these bending transitions to be observed up to the fourth overtone transition. jg p.1
