Simplification of calculations of MAS-NMR signals. A set of polynomials were derived by which sideband intensities and time-domain signals can be calculated very simply in comparison to formerly-known numerical algorithms. FID and spectra of related experiments can be predicted by modifications of this approach.
Mathematical aspects of time evolution of NMR signals under MAS. Corresponding to the Liouville-von Neumann equation, the time evolution of the density matrix is described by systems of linear differential equations with non-constant coefficients. Analytical solutions cannot be obtained in the general case. Numerical procedures are known which however in some cases do not give accurate results, for example close to the so-called recoupling condition. Aim of this work is to improve the appoximations or - if possible for a particular case - obtain an analytical solution.
