Abstract
The Mn(II)-ATP system has been investigated at the light of new electron spin relaxation findings. A dynamic model, taking into account a distribution of correlation times, is suggested. Namely transverse and longitudinal nuclear relaxation times are analyzed in connection with new values of the electron spin relaxation time. A reinvestigation of NMR and EPR results is tempted as a consequence of the new model. The combined NMR and EPR analysis allows an unambiguous interpretation of nuclear paramagnetic relaxation rates and points out the direct involvement of N(7) in the metal binding. © 1978, American Chemical Society.
