The 3D localized 13C spectroscopy methods LINEPT and LODEPT, which are modifications of INEPT and DEPT, are proposed. As long as a 13C inversion pulse (180-degree pulse) is applied at 1/(4J) before the proton echo time in LINEPT and a 13C excitation pulse (90-degree pulse) is applied at 1/(2J) befor

The polarization transfer in the DEPT experiment is analysed as a function of transfer time A and variable pulse angle 8 for a spin system Zm I:. Zg S. This DEPT experiment applied to 29Si NMR may be tuned for optimum sensitivity and quantitative information and then used as an editing method for th
## Abstract The application of a nonβrefocusing INEPT pulse sequence in ^119^Sn NMR spectroscopy allows the determination of ^n^__J__(^119^Sn, ^1^H) values by comparison of the observed patterns with calculated spectra. It gives an easy access to ^n^__J__(^119^Sn, ^1^H) values in butyltin derivativ
Diffusion-ordered NMR spectroscopy (DOSY) has been dure, of course, leads to confusing results when peaks overused in the analysis of a variety of complex mixtures, e.g., lap, but can be justified when overlap is rare. Furthermore, samples containing large numbers of monodisperse compothis method ca
