β¦ Synopsis
The quadrupole coupling constant and asymmetry parameter of a *H MAS NMR spectrum can be derived by computer simulations of the spinning sideband pattern. Off angle spinning causes complex lineshapes which can be used to find approximate quadrupole parameters and to determine more accurately the asymmetry.

Spinning sidebands (SSBs) in the MAS NMR spectrum of a polycrystalline solid are related to the principal values of the chemical shift or quadrupole coupling tensors. At present, 2D methods are widely used to sort out the SSBs for each isotropic peak. Here a simple and efficient method for separatin
New methods for optimum separation of (2)H MAS NMR spectra are presented. The approach is based on hypercomplex spectroscopy that is useful for sign discrimination and phase separation. A new theoretical formalism is developed for the description of hypercomplex experiments. This exploits the proper
