The emission lifetime, tao, and its temperature dependence is reported for aqueous CrNH35CN2 and trans-CrNH34CN2. The tao values at 20 degrees C are 22 microseconds and 65 microseconds for pH 3 solution, respectively, and the corresponding activation energies are 111.2 kcal mole and 11.6 k cal mole. The results are discussed in terms of previously suggested emission rules. The emission, presumably from the lowest doublet thexi state is in both cases quenched by hydroxide ion at about a diffusion controlled rate. Author
