Abstract
The 13C chemical shifts and the increments (Δδ) of the SCH3 group in the NMR spectra of S-methylquinolines were measured. It is shown that the chemical shifts of S-methylquinolines correlate satisfactorily with the total charges on the carbon atoms calculated within the CNDO/2 approximation. The coupling of the SCH3 group with the quinoline ring was examined on the basis of the Δδ values.
