Theoretical Molecular Biophysics Theoretical Molecular Biophysics is an advanced study book for students shortly before or after completing undergraduate studies in physics chemistry or biology. It provides the tools for an understanding of elementary processes in biology such as photosynthesis on a molecular level. A basic knowledge in mechanics electrostatics quantum theory and statistical physics is desirable. The reader will be exposed to basic concepts in modern biophysics such as entropic forces phase separation potentials of mean force proton and electron transfer heterogeneous reactions coherent and incoherent energy transfer as well as molecular motors. Basic concepts such as phase transitions of biopolymers electrostatics protonation equilibria ion transport radiationless transitions as well as energy and electron transfer are discussed within the frame of simple models.
