| Abstract: | 2,7-di-tert-butyl and 2,7-di-tert-butyl-4-ethoxy-carbonylthiepins exhibit a similar spectroscopic profile in their absorption and the magnetic circular dichroism spectra. A quantum-mechanical calculation based on the INDO method gave a theoretical interpretation of the spectra, which were all ascribed to the π→π* electronic transitions characteristic of the thiepin skeleton. |
