Pelargolactam (1-azacyclodecan-2-one) was studied by 1H and 13C NMR spectroscopy in solution between 25 and −145°C. Equilibrium solutions of pelargolactam at 25°C consist mainly of the trans isomer together with 5–10% of the cis isomer. Solid p

The conformational properties of enantholactam (1-azacyclooctane-2-one) in solution were studied by 1H and 13C NMR at various temperatures. Only the cis-isomer is present and it occurs in two different conformations in the ratio 3:2, as observed by 1

The equilibrium mixture of the cis and trans isomers of caprylolactam (1-azacyclononan-2-one), was studied by 1H and 13C NMR spectroscopy at various temperatures. The exchange between corresponding carbons in the two isomers in solution was studied b

The conformation of e-caprolactam (1-azacycloheptan-2-one) was studied by low-temperature 2 D 1 H and 13 C NMR. Only one conformer was found in solution from the 13 C NMR spectra recorded down to -155 o C. This conformer was shown, by infrared spectr
