چکیده
* Address for correspondence: PL-84200 Wejherowo, ul. Gen. W. Sikorskiego 11, Poland. the increments in the dipole moments, A/J, determined for different fluorescent molecules, based on the LippertMataga solvent polarity parameter are much overrated in comparison to the values /ue obtained by electrooptical methods [7-10], In the present paper we determine the dipole moments ,ug and yue of P R O D A N by the "solvent perturbation method" [8, 11], utilizing the absorption and fluorescence shifts in different solvents measured by Catalan et al. [4].

Ground and Excited State Dipole Moments of BADAN and ACRYLODAN Determined from Solvatochromic Shifts of Absorption and Fluorescence Spectra
The electric dipole moments in the ground g and excited states e of the fluorescent probes BADAN (6-bromoacetyl-2-dimethylamino-naphthalene) and ACRYLODAN (6-acrylolyl-2-dimethylaminonaphthalene) are determined from the solvatochromic shifts of their absorption and fluorescence spectra for two Onsager interaction radii (a = 4.2 and 4.6 Å). The obtained values of g and e for BADAN are comparable...

In our previous work [1], the dipole moments of BADAN (6-bromoacetyl-2-dimethylamino-naphtalene) and ACRYLODAN (6-acrylolyl-2-dimethylaminonaphtalene) in the ground mg, and excited me, state, have been determined, using the solvatochromic method. These molecules are similar in shape to PRODAN (6-propionyl-2-dimethylamino-naphtalene). It has been found that in the case studied the values me/mg f...

متن کاملSteady-state absorption and fluorescence study: Dipole moments of coumarins
The absorption and fluorescence spectra of 7-dimethylamino cyclopenta [c] coumarin (C138) and 4-methyl-piperidino [g] coumarin (C339) dyes were measured in neutral, aprotic and protic solvents. Solvatochromic shifts of absorption and fluorescence as a function of different solvent polarity parameters (bulk as well as microscopic) were analyzed for these dyes and the ground state dipole moment (...

The Ultraviolet-visible (UV) spectra of toluene, ortho-bromo and para-bromo toluene in different solvents have been studied. The electric dipole moments and polarizabilities in the molecular excited electronic states were determined. It was found that the electric dipole moments for the excited states (µ*) and the ground states (µ) of these compounds are equal, and the change in dipole moment i...
