Abstract

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

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
