| Popis: | FTIR spectral analysis of solvation effects on the absorption frequencies of N H stretching vibrations of pyrrole as well as its complexes with proton acceptors (B) was carried out. The comparative analysis of the influence of solvation effects on the absorption frequencies of N H groups of pyrrole and O H groups of methanol in aprotic solvents for both free and bound molecules was carried out. The process of transferring the complexes to proton donor solvent, chloroform, which leads to a change in the strength of X H…B (where X = O or N) hydrogen bonds due to the manifestation of cooperative interactions was studied. Contribution of the cooperativity effect of pyrrole and methanol complexes was found to differ. |
