In this work, several exact and approximate analytical solutions to the quantum master equation are derived using both classical and non-classical coupling models to describe the kinetics of Hartmann-Hahn cross-polarization (HHCP) and multiple-contac

Hartmann-Hahn cross-polarization (HHCP) is the most widely used solid-state NMR technique to enhance the magnetization of dilute spins from abundant spins. Furthermore, as the kinetics of CP depends on dipolar interactions, it contains valuable infor

Multiple-contact cross-polarization (MC-CP) is applied to powder samples of ferrocene and l-alanine under magic-angle spinning (MAS) conditions. The method is described analytically through the density matrix formalism. The combination of a two-step

We present a new simple and robust cross-polarization (CP) scheme, called ROtor-Directed Exchange of Orientations CP (RODEO-CP), which permits to obtain undistorted chemical shift powder spectra with short contact times, i.e., when a (quasi-)equilibr

Using the Anderson-Weiss (AW) formalism, analytical expressions of the NMR signal are obtained for the following magic-angle spinning (MAS) experiments: total suppression of sidebands (TOSS); phase adjusted spinning sidebands (PASS); rotational-echo

Gel networks prepared from aqueous melamine-formaldehyde resins via a sol-gel route were characterised by 13 C CPMAS (where MAS stands for magic angle spinning)-NMR and T 2 relaxation. We show that within the aqueous networks, the type and amount of

The REDOR and CPMAS techniques are applied for measuring 13C15N dipolar coupling constants in glycine. It is shown that the selective CP or SPECIFIC CP technique removes the coherent evolution of the spin system under homonuclear 13C13C J couplings.

A simple analytical method based on the memory-function approach and the Anderson-Weiss theory is presented for studying in a uniform way the spin dynamics in several NMR experiments performed under the conditions of magic-angle spinning (MAS). A ser
