Figure 4From: Mg spin affects adenosinetriphosphate activitySpin states appearing upon interaction of the T 1 and T 2 PESs around the crossing. (1) corresponds to the production of a spin-separated state followed by ATP cleavage according to the ion-radical mechanism; (2) and (3) correspond to the production of the metastable, S3 and S2, states suggesting their further transformations into S4 and S1.Back to article page
