# Multidimensional femtosecond spectroscopy

## Location: MPI-PKS, Seminarroom 3

Time: Thursday 13:00 - 14:30

Femtosecond spectroscopy has become a standard tool to investigate the dynamics of molecular systems. In multidimensional femtosecond spectroscopy one uses several femtosecond pulses with varying time delay between them.
In this lecture the basic formalism is derived and specific experimental techniques are discussed.

# Non-linear optical spectroscopy

## New Location and Time.

** Location: MPI-PKS, Seminarroom 3 **

Time: Thursday 10:45 am - 12:15 am (SS 2013)

Non-linear optical spectroscopy is used in many areas of physics, chemistry and biology.
It allows one to obtain information on quantum dynamics on the fs-scale.
One of the prominent examples is the observation of long lasting coherent beatings in photosynthesis.
In this lecture the basic formalism is derived and specific experimental techniques are discussed.
