Abstract
The pathways of fragmentation of thiacarbocyanine dyes with various electron-donor substituents in the meso position of the polymethine chain under the influence of high temperatures and electron impact were investigated. The results of thermolysis of the dyes are compared with the results of quantum-chemical calculations of the labilities of the bonds in the molecules.
