Abstract

The analysis of the overlapped bands in UV-Vis absorption spectroscopy provides valuable information about the structure of the molecule and its environment. The resolution of individual bands in the UV-Vis region is a complicated task since the absorption bands are generally strongly overlapped, they have different half-band widths, and their number is difficult to estimate. In the present study the possibilities of using Levenberg's method for analysis of overlapping bands in UV-Vis spectroscopy are discussed, and a logical algorithm for their resolution is developed. This approach is applied to the analysis of the vibrational structured long-wavelength bands of <i>trans</i>-stilbene and its derivatives.
