Experimentelle und Quantenchemische Untersuchungen der Dipolmomente von Donator-substituierten 4-Isocyanat-trans- Stilbenen im nichtrelaxierten angeregten Singulettzustand

Abstract

Abstract The electric dipole moments of 4-isocyanate-4′-dimethyl-amino-trans-stilbene(I), 4-isocyanate- 4′-methoxy-trans-stilbene(II) and 4-isocyanate-3′,4′-dimethoxy-trans-stilbene(III) in the relaxationless first excited singlet state (μe) have been determined from the solvent effect and compared with the values calculated with the quantum chemical Parisser-Parr-Pople method.
