## Abstract The SELective INverse detection of carbon–proton CORrelation pulse sequence that yields a 1D spectrum of a proton directly bonded to a selected carbon resonance has been converted into a proton and carbon double‐selective variant that provides a ^1^H spectrum of a selected proton that i
A m d i e d version of the two-dimensional semiselective INEPT experiment is presented which allows the determination of long-range protowarbon couplings in medium-sized molecules. The difference in the TI relaxation times is utilized for the reduction of the number of protons from which coherence i
A new technique is described which enables accurate values of heteronuclear long-range coupling constants to be obtained from highly distorted multiplets in two-dimensional correlation spectra. The technique uses a simple data fitting of the distorted multiplet with a model obtained from the convent
