- W2293539062 abstract "Lifetimes for doublet state emission of reineckate ion, trans-Cr(NH3)2(NCS)4(-), in room temperature solution are reported for twenty solvent media and as a function of solvent composition in water-acetonitrile mixtures. These vary from 6 nsec in water to 204 nsec in sulfolane (and 460 nsec for the solid potassium salt). Apparent activation energies for emission were determined in twelve systems and range from 10 to 18 kcal/mole. Both the emission spectrum and the doublet state absorption spectrum are given for acetonitrile as solvent. The excited state kinetic scheme is discussed in terms of these and other data, and it appears likely that at room temperature the emission lifetimes are determined primarily by the rate at which the doublet excited state undergoes chemical reaction.
