Infrared vibrations of carbon-sulphur bonds in bis(benzoxazole-, benzoimidazole-benzothiazole-2-thiol)methane. Assignments by "selenation"

Article abstract of DOI:10.1016/0584-8539(83)80069-5

The i.r. spectra of the title compounds have been compared with those of the corresponding-2-selenol derivatives.The i.r. vibrational assignments of the thioether links have been made on the basis of the selenation.The moiety CH2-(Y-CH2<*>)2 (Y = S, Se) present in all the compounds considered gives typical absorptions in the fingerprint region.
