Abstract
The ^13^C NMR spectra of a series of 1โsubstituted imidazoles were measured and assigned on the basis of substituent chemical shifts and ^13^C/^1^H shift correlated spectra.

## Abstract ^13^C NMR data are reported for new __N__โbenzyl and __N__โalkyl derivatives of 3โazachalcone. The unambiguous assignment of signals is based on ^13^C/^1^H heteroshift correlated 2D NMR spectra.
The "C NMR chemical shifts for a series of substituted tricycle[ 5.3.0.02.6] decan-3-ones and tricycle[ 5.4.0.02~6]undecan-8-ones derived from [ 2 + 21 photoaddition reactions are assigned and the influence of various substituents is discussed. In general, it was found that substituent shifts are le
## Abstract ^1^H, ^13^C and ^17^O NMR spectra for 22 substituted nitropyridines were measured and their ^1^H NMR spectra were analysed. The most significant variations in the NMR parameters are found for isomeric hydroxy derivatives, owing to the possibility of ketoโenol tautomerism. The prevalence
## Abstract The ^13^C NMR spectra of several 2โsubstituted imidazoles and benzimidazoles have been measured. The substituent was CH~3~, COOH and CONHR, where R = H, __n__โBu, __p__โtolyl or __m__โchlorophenyl. Carbons 4 and 5 in the imidazoles and the carbon pairs 8/9, 4/7 and 5/6 become equivalent
The 1 H and 13 C NMR spectra of seven 2-substituted phenyl methyl sulphides were measured and their chemical shifts assigned on the basis of two-dimensional NMR techniques such as H,H-COSY and C,H-COSY. The chemical shifts of these sulphides were correlated with the appropriate SCS values of monosub
