Abstract
The reconstruction of angular distributions from two-dimensional (2D) magnetic resonance spectra of powders is described. The analysis involves no model assumptions and is applicable to 2D exchange NMR as well as 2D nutation exchange NQR. The proposed method is based on the constrained analysis of selected dominant ridges of a 2D powder spectrum. Practical applications of the proposed technique are demonstrated with experimental 13C 2D exchange NMR spectrum of dimethylsulfone and calculated 35Cl 2D nutation exchange NQR spectra of chloral hydrate. Rotational angle distributions for methyl groups in dimethylsulfone and CCl 3 group in chloral hydrate have been found. The chemical shift anisotropy of 13C in dimethylsulfone was determined with high accuracy from 2D exchange NMR powder spectra.
