Solvent effects on rate constants and activation enthalpies and entropies for the anation of [Cr(NH3)sH20] 2+ by SCN-in aqueous mixtures of MeOH, EtOH, i-PrOH and t-BuOH were analysed into initial and transition state contributions. From kinetic measurements, solubilities of the complex salt and ent
Luminescence Lifetimes of several complex ions at 77% and 4.2'K arc reported. The Lifetimes are shortened in a magnetic field. The results indicate that emission occurs from scvera! states in Boltzmann equilibrium, at least one of which possesses a magnetic moment.
