Given that the time to photobleaching of each fluorescent molecule in an ensemble has an exponential probability distribution, show that the photobleaching of the ensemble is described by an exponential decay function.

Determine the effective absorption cross sections for the dyes FITC and TRITC, assuming their molar extinction coefficients are as given in Section 8.5.2.
