“…Using restricted active space configuration interaction (RASCI) wave functions, Rodri ́guez-Jimeńez, Carreras, and Casanova at the Donostia International Physics Center in Spain explore the origin of these couplings and introduce a new definition of the SOC constant for molecular aggregates. 32 Next, Villegas-Escobar, Hoobler, Toro-Labbe, and Schaefer at the Pontificia Universidad Catoĺica de Chile and the University of Georgia examined the reactivity of low-valent aluminyl ions toward H 2 through a series of coupled cluster calculations. 33 They found that aluminyl systems with carbonand nitrogen-based chelating centers would serve well to activate hydrogen without dimerization.…”
