I'd like to know if there are further NMR spectroscopic methods to detect NH---O hydrogen bond in N-(2-methoxyphenyl)benzamide compounds. I know about HNCO techniques, but they are specifc for carbonyl carbon. I have already tried to reveal any amide proton chemical shift variation with temperature and to measure the 1JNH by 1H,15N HSQC spectra, but I don't think these observables could be sufficient to show any scalar coupling between the methoxy oxygen and the amide proton.
