Though the Ernst angle concept presented in the original paper introducing Fourier NMR spectroscopy was developed for sensitivity optimization in a time-averaged single-pulse experiment it is shown here that its conclusions may be generalized to comp

Abstract It is shown how the resolution in SEA XLOC NMR spectra for distinguishing between heteronuclear two‐ and three‐bond correlations for all 13C multiplicities can be improved by a modified experiment delivering absorptive profiles in the in

The origin of HSQC artifacts in proton-detected INADEQUATE (PDI) NMR spectra is presented along with a remedy for their suppression.

The NMR experiment design strategy of NO Relaxation Delay (NORD), introduced mostly as an idealized theoretical approach, is extended and put to practical use by considering synergy and sensitivity-balance in concatenation of experiments. It is illus

The NMR pulse sequence design strategy of NORD (NO Relaxation Delay) is extended to design of two new three-module experiments, NORD {HMBC}-{HSQC-TOCSY}-{TOCSY} and NORD {HMBC}-{2BOB}-{TOCSY}, each delivering four spectra - HMBC, HSQC, TOCSY, and eit

It is shown how the same pool of magnetization can be tapped twice in two different concatenations of three experiments into a single pulse sequence with only one relaxation delay. This is accomplished by using the BANGO pulse sequence element twice

Two new related methods, 2BOB and H2OBC, for tracking out the backbone of protonated 13 C nuclei are presented. 2BOB extracts an H2BC and an HSQC-type spectrum from one and the same data set, and the combined information of these two spectra tracks o

Novel NMR experiments, BANGO SEA XLOC–H2OBC or BANGO HMBC–H2OBC, can deliver complete heteronuclear correlation maps on a time scale of minutes for small molecules. By way of example, it is demonstrated that all intra- and inter-residue 1H and 13

A novel two-dimensional method, SEA XLOC, for distinguishing between two- and three-bond correlations in heteronuclear NMR spectroscopy is introduced and demonstrated on ibuprofen and by a complete set of correlations with a simple and most complex q
