INVESTIGATION OF THE PATHWAYS OF THERMAL FRAGMENTATION OF THIACARBOCYANINE DYES

Khesin, V. G.,Al'perovich, M. A.,Abramenko, P. I.

, p. 1187 - 1192 (1981)

The pathways of the thermal transformations of thiacarbocyanines with various alkyl groups attached to the ring nitrogen atoms of the heteroresidues, of 3,3'-diethylthiacarbocyanine with various anions, and its anhydro base were investigated.The results of the studies are compared with the results of quantum-chemical calculations of the labilities of the bonds in these compounds by the Pariser-Parr-Pople method.
