THEORETICAL-STUDY OF ROTATIONAL-ECHO DOUBLE-RESONANCE AND RELATED EXPERIMENTS

This paper discusses the theory of the rotational-echo double-resonance (REDOR) and related experiments by using a different approach than that used by previous researchers. The theory has been used to discuss the REDOR, rotational-echo double-resonance total sidebands suppression (REDORTOSS), and interrupted REDOR experiments. In the case of REDORTOSS experiment, an analytical solution has been derived which ensures that the quantification of the dipolar coupling constant and therefore the measurement of the distance between two anisotropic heteroatoms can be made. An alternative REDOR method for situations in which anisotropy is a problem is also proposed, called the interrupted REDOR. © 1994 American Institute of Physics.
