Abstract
The band shape observed for the 3A2g --> 3T1g(3F), 1Eg crystal field transitions (1) in the UV-NIR absorption spectrum of Ni(H2O)62+ is analyzed with a time-dependent theoretical model and visualized in this electronic publication. The importance of fast intersystem crossings is illustrated by our animations, as is the influence of the positions of the excited-state potential energy surfaces, along both the energy and the normal coordinate axes (2). The model quantitatively reproduces the experimental spectrum between 550 and 900 nm and illustrates the important symmetry and bonding information that can be obtained from electronic spectra of transition metal compounds.
