Spectral-luminescent properties of laurdan molecule.
Quantum-chemical calculations of ground and excited states of fluorescent probe (laurdan) by ab initio and semiempirical methods were performed. The laurdan optimized geometries of S0 and S1 states were obtained. The influence of laurdan nonrigidity structure on dipole moments and location of energy levels were studied. The specific solvation centers of laurdan were obtained. The rate constants of photoprocesses and fluorescence quantum yield of laurdan in non-polar solvent were calculated.
