Abstract
Femtosecond spectroscopies of chlorophyll dimers and the LH2 antenna c omplex are calculated using a theory that incorporates the effects of two-exciton states, static disorder and coupling of excitons to phonon s with an arbitrary spectral density. Applications are made to pump-pr obe and echo peak-shift measurements in the B820 dimers. and to fluore scence depolarization in the B850 system of the LH2 antenna of purple bacteria.
