Photochemistry and Photophysics of Aqueous Cr(NH3)5(CN)(2+) and Trans-Cr(NH3)4(CN)(2+).
Abstract
The emission lifetime, tao, and its temperature dependence is reported for aqueous Cr(NH3)5(CN)(2+) and trans-Cr(NH3)4(CN)(2+). The tao values at 20 degrees C are 22 microseconds and 65 microseconds for pH 3 solution, respectively, and the corresponding activation energies are 1/11.2 kcal mole and 1/1.6 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)
