Responsible coordinator of the module PH2187 is Philipp Scherer.

Content, Learning Outcome and Preconditions


Fermi's Golden Rule
Electron-Phonon coupling

Intramolecular transitions:
radiative (absorption, fluorescence)
radiationless (internal conversion, intersystem crossing)

Coherent electronic excitations
( molecular aggregates, polymers)

Incoherent energy transfer
(Förster-transfer,  disorder)

Electron transfer
(Marcus' Theory, charge transfer in DNA)

Proton transfer

Learning Outcome

After the course, the participants are able to describe elementary processes in molecular systems on the basis of quantum mechanics.

They are able to describe elementary models for coherent and incoherent energy transfer, electron and proton transfer and to apply these to molecular systems.

The lecture "quantum methods for molecular systems" is complementary but not a requirement

Module Exam

Description of exams and course work

In an oral exam the learning outcome is tested using comprehension questions and sample problems.

In accordance with §12 (8) APSO the exam can be done as a written test. In this case the time duration is 60 minutes.

Exam Repetition

There is a possibility to take the exam at the end of the semester.

Condensed Matter

When atoms interact things can get interesting. Fundamental research on the underlying properties of materials and nanostructures and exploration of the potential they provide for applications.

Nuclei, Particles, Astrophysics

A journey of discovery to understanding our world at the subatomic scale, from the nuclei inside atoms down to the most elementary building blocks of matter. Are you ready for the adventure?


Biological systems, from proteins to living cells and organisms, obey physical principles. Our research groups in biophysics shape one of Germany's largest scientific clusters in this area.
