| Abstract: | A new formalism for describing the evolution of density operators was proposed. It can evaluate the evolution of density operators of strongly and weakly coupled spin systems in a u-nified way, and describe the experiments involving weak RF pluse. Some problems were explicitly treated including spin tickling, isotropic mixing in systems of two coupled nuclei (I= 1/2), dipolar evolution and strongly coupled AB and ABX spin systems. |
