- Opis:
- The electric dipole moments μ$\text{}_{e}$ in the lowest excited singlet state of nine short-lived para-disubstituted trans-stilbenes were determined experimentally based on the effect of the external electric field on the fluorescence anisotropy. The values of μ$\text{}_{e}$ obtained from Liptay's theory with the employment of the Onsager effective field are in satisfactory agreement with those calculated based on the solvatochromic effect. In the case of para-substituted trans-stilbenes with the same donor substituent R = N(CH$\text{}_{3}$)$\text{}_{2}$ in position 4 and different acceptors R' in position 4', the enhancing electron properties of the acceptor are accompanied by the increase in μ$\text{}_{g}$ - the dipole moment in the ground state, and μ$\text{}_{e}$ - the dipole moment in the excited state. There exists a linear relation between the values of μ$\text{}_{e}$ and μ$\text{}_{g}$.
