Abstract
A method for transforming a 2D exchange spectrum into an orientation representation is proposed which is based on finding the reorientation probability as a function of angles. A procedure of evaluation and analysis of two-dimensional magnetic spectra of powders is described and a method for finding the asymmetry parameter from 2D exchange spectra is proposed. The capabilities of the method are illustrated for a model 35Cl 2D nutation exchange NQR spectrum of chloral hydrate CCl3CH(OH)2 and an experimental 13C 2D exchange NMR spectrum of dimethylsulphone CH3–SO2–CH3. The asymmetry parameter of the chemical shift tensor for this compound is determined.
