Abstract
Analysis of the IR, UV and 1H-, C-13-NMR spectra and the dipole moments ind icated that the secondary 1-methyl-2-pyrrolecarbothioamides are non-planar and exist in the trans (Z)-s-trans conformation. The results were compared with those obtained previously for analogous 2-thiophene- and 2-furanecarbo thioamides. The influence of the heterocyclic core on the conformation of t he secondary carbothioamides was shown.
