The Inertial Effect in Rotational Fluorescence Depolarization
نویسندگان
چکیده
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 10" 3 Pa • s to 0.993 x 10"* Pa • s) and diphenylenestilbene (DPS) in different solvents, a semi-empirical equation is proposed, yielding moments of inertia that are only two to five times higher than those estimated from the molecular geometry.

متن کاملPrecision and Reliability Incensement of Inertial Navigation System with Rotation and Redundancy
Precision and reliability are two main performance characteristic in low-cost Inertial Navigation System(INS). Increase of precision in low-cost INS without auxiliary sensors is main challenge. Bias instability leads to position drift error in inertial navigation system. In addition, fault occurrence makes the sensor reliability is decreased. Rotation of Inertial Measurement Unit(RIMU) and use ...
متن کاملOrientational exchange approach to fluorescence anisotropy decay.
Fluorescence depolarization is a powerful technique in resolving dynamics of molecular systems. Data obtained in fluorescence depolarization experiments are highly complex. Mathematical models for analyzing data from depolarization due to rotational motion have been largely based on the rotational diffusion equation. These results have been verified by Monte Carlo simulations. It has been impli...
متن کاملA high resolution fluorescence decay and depolarization study of human plasma apolipoproteins.
Human plasma apolipoprotein A-I (apoA-I) and apolipoprotein C-I (apoC-I) were investigated by time-resolved fluorescence decay and depolarization. The tryptophyl fluorescence of apoAI undergoes a double-exponential decay with lifetimes of 1.07 and 3.43 ns which remain unchangcd over the range of apoA-I concentration studied. The time-resolved fluorescence of both native and denatured forms of a...
متن کاملFree hydroxyl radical dosimetry by using 1 MHz low level ultrasound waves
ABSTRACTBackground : In order to quantify effects of ultrasound irradiation parameters under therapeutic condition, especially sonodynamic therapy, it is initially necessary to evaluate inertial cavitation activity in vitro conditions therefore, in this study, the effect of 1 MHz low level ultrasound based on °OH radicals generated by acoustic inertial cavitation in aqueous solution was monit...
