In this paper, which is based on the materials presented at the Bielefeld workshop on Molecular Structure and Energy Scrambling, I would like to focus on the problems pertaining to energy and phase randomization in large molecules. Specifically, I would like to discuss the following major problems: a) electronic dephasing as manifested in the interactions between large-molecules in different electronic states and a bath of dense low-frequency modes. b) vibrational dephasing as manifested in the dynamics of localized vibrational energy in real large molecules. c) population and phase changes in multi-level systems (optical T1 and T2).
