摘要

Absorption spectra of octahedral nickel(Ⅱ) complexes are used to illustrate that the limitation to only the initial and Born-Oppenheimer final states of an electronic transition is not adequate in order to rationalize the intensity and vibronic structure of the lowest-energy spin-forbidden transition of these compounds. Qualitative and quantitative models are applied and discussed for a series of absorption spectra measured in solution at room temperature and for the low-temperature single-crystal absorption spectra of nickel(Ⅱ) ions doped into bromide host lattices. The spectra and models illustrate the influence of multiple allowed transitions on the lowest-energy spin-forbidden band.
