The density matrix method is well known for being useful to theoretically treat complicated phenomena. In this work, this method will be applied to study the ultrafast energy and electron transfers in photosynthetic reaction centers. We present a microscopic model to describe the spectroscopy and dynamics for photosynthetic bacterial reaction centers (RCs). In this model, we propose eight vibrational modes and their Huang–Rhys factors for different electronic states, and the couplings between the electronic states. As applications, we have constructed steady‐state and ultrafast time‐resolved spectra for the wild‐type RC of Rhodobacter ( Rb .) sphaeroides . © 2000 John Wiley & Sons, Inc.
