Time Dependent Fluorescence Depolarization Studies of Bbot
The generally used model for rotational diffusion, the Perrin-Stokes-Einstein model [l-3] , is based on hydrodynamics with the “stick” boundary condition. That is, the velocity of the solute molecule surface relative to the nearest solvent molecules is zero. Recently Hu and Zwanzig [4] have derived rotational friction coefficients for spheroids with the “slip” boundary condition. Here, the resi...
متن کاملThe Inertial Effect in Rotational Fluorescence Depolarization
The influence of the moment of inertia on the rotational fluorescence depolarization is discussed. Based on experimental results obtained for five luminescent compounds: 2,5-diphenyloxazole (PPO), 2,2'-p-phenylene-bis(5-phenyloxazole) (POPOP) , p-bis[2-(5-a-naphthyloxazolyl)]-benzene (a-NOPON), 4-dimethylamino-a)-methylsulphonyl-trans-styrene (3 a) in n-parafines at low viscosity (from 0.22 x 1...
متن کاملThe fluorescence depletion spectroscopy of CdCH3
The fluorescence depletion spectroscopy technique has been applied to the à 2E electronic state of the CdCH3 radical to investigate “dark” vibronic levels. The observed FDS spectrum complements the sparse laser induced fluorescence and resonance-enhanced multiphoton ionization spectra. Both the upper and lower spin components of the vibrationless level as well as excitations involving the symme...

متن کاملComputer simulation of fluorescence depolarization due to brownian motion.
A computer program has been written to simulate the Brownian motion of rigid fluorescent molecules. The time dependence of the fluorescence polarization anisotropy as generated by this simulation is in agreement with that predicted by the recent theoretical treatment of Belford, Belford, and Weber (Proc. Nat. Acad. Sci. USA (1972) 69, 1392-1393). The program thus serves as a verification of the...
