| Abstract: | The 13C, 1H-NMR, IR, MS spectra were measured for the seven N-methyl-3-alkyl-pyrrolidones.The NMR spectral lines were assigned, and the molecular structures were determined.The alkyl substituent empirical parameters for the calculation of pyrrolidone 13C chemical shifts and the pyrrolidone substituent empirical parameters for the alkyl 13C δ values were obtained. |
| |
| Keywords: | Alkyl pyrrolidone ~(13)C ~1H-NMR Empirical parameter. |
