## Abstract Experimental and theoretical studies carried out to investigate the influence of strong coupling effects in the spectra generated through the commonly used heteronuclear chemical shift correlation (HETCOR) sequences involving a constant evolution time are reported. It is seen that the s
Enhanced versions of heteronuclear chemical shift correlation experiments which yield high-quality spectra with efficient suppression of extra peaks arising from strong coupling effects are proposed. The enhanced pulse sequences feature properly designed filtering schemes inserted during preparation
Ψ1 , respectively. The results for the residual dipolar interactions were verified by repeating the above measurements at a temperature of 1.5Β°C, where the spectra of the H 2 O molecules were well resolved, so that the 1 H-1 H dipolar interaction could be determined directly from the observed splitt
