Design of a fluorescence technique using double laser pulse excitation for the measurement of molecular Brownian dynamics
A complete analysis of a novel method to evaluate the rotational diffusion time of fluorescent molecules is presented. It is based on the study of the total fluorescence produced after excitation with two consecutive short laser pulses. Expressions for the total fluorescence energy emitted in this c...
