fishbonett <')+++< is a Python package for propagating the dynamics of multi-site vibronic model systems that have fishbone-like configurations. The motivation of the fishbone-like configurations of this specific type of models is very simple; we would like to study the dynamics of electron-transfer or excitation-energy-transfer systems, in which each electronic or vibrational site is coupled to a bath.
