Zur Relaxation eines Kernspinpaares bei behinderter Bewegung

Authors


Abstract

Redfield's density matrix theory has been applied to a pair of equal spins rotating around a fixed axis. The results of Bloembergen's wellknown paper [1] were corrected. For calculating the spectral densities of the stochastic rotational motion the theory of Ivanov and Valjev [2] has been used which holds for large rotational jumps between equal potential wells. The formulae are compared with the results of Look and Lowe [3] for the hindered molecular rotation between unequal potential wells.
