Features of determining pure-electronic transition from diffuse absorption or emission spectra at low temperatures
Abstract
It is shown that as low temperature narrows the population of “hot” active in antistokes transition molecules, it results in narrowing of range, where by this method the pure electronic transition is localized. As the result, the sensibility to chromophore inhomogeneity is growing. The examples of the pure electronic transition frequency determination from experimental absorption and emission spectra at low temperature are presented.
