Infrared spectra in the 1700-500 cm-1 region have been studied for several types of thiopiperidides (thiobenzoylpiperidides, thiocinnamoylpiperidides and phenylthioacetpiperidides) and for the corresponding thiomorpholides.Three characteristic thioamide bands were located and assigned.The behaviour of these bands on molecular complexing (with iodine as an electron acceptor) was used to support the assignments.The experimental data were discussed in terms of the theoretical results obtained by an HMO procedure.
