Mixed-valence systems, stationary

DR. PAUL SCHATZ (University of Virginia) I think I know what Dr. Meyer meant in his talk, but all mixed-valence systems have stationary states. For example, consider the ammonia molecule. It tunnels back and forth between two umbrella forms, 9 10... [Pg.151]

DR. SCHATZ All mixed valence systems have stationary states. In any such state the probability distribution is time independent. Hence, it is incorrect to say that a mixed valence state is inherently time dependent. [Pg.152]

Larsson and co-workers have used relation (18) to calculate Tjb for organic molecules in which two centers are bridged by saturated groups [65,66], and for mixed valence systems [67]. The stationary states /i and /2 are determined by a CNDO/S method, with extensive configuration interaction and use of semi-empirical parameters. The nuclear configuration Q where relation (18) is valid is adjusted so as to satisfy the delocalization property expressed by (17). These... [Pg.18]
