A stochastic Liouville-von Neumann approach to solving a spin-boson model is applied to electronic energy transfer in Fenna-Matthews-Olson (FMO) complexes as a case study of the dynamics in biological systems. We modify a noise generation method to treat an experimentally obtained highly structured spectral density. By considering the population dynamics in a two-site system with a model structured spectral density, we numerically observe two kinds of coherent motions associated with inter-site coupling and system-bath coupling, the latter of which is mainly attributed to the peak structure of the spectral density.
