Infrared Spectra of Polybutadienes [PDF]
AbstractIt is shown, by analytical resolutions of the spectra of isomerized cis‐1,4‐polybutadienes, that the band due to hydrogen out‐of‐plane vibrations of cis‐CHCH groups appears at 740 cm.−1 and that the apparent shift of this band to lower frequencies, as the amount of cis‐CHCH decrease in a polybutadiene, is due to the presence of other bands in
