  1. Multi-dimensional spectroscopy Thomas la Cour Jansen Zernike Institute for Advanced Materials University of Groningen

  2. Shakespeare - Hamlet - 1600 2D or not 2D??? Han-sur-Lesse 2009 - Thomas la Cour Jansen

  3. Outline Why do multi-dimensional spectroscopy? Examples from the real world. Phenomena: Spectral diffusion Rotation Population transfer Structure: Peptides/Proteins Dynamics: Chemical exchange Water Han-sur-Lesse 2009 - Thomas la Cour Jansen

  4. Motional narrowing cos( ω t ) exp( − t 2 / τ 2 ) Frequency Time cos( ω t ) exp( − t/ τ ) Kubo, J. Math. Phys., 4 :174 (1963) Han-sur-Lesse 2009 - Thomas la Cour Jansen

  5. Spectral diffusion Han-sur-Lesse 2009 - Thomas la Cour Jansen

  6. Rotational dynamics Anisotropy: Han-sur-Lesse 2009 - Thomas la Cour Jansen

  7. Peptides/Proteins • Amide CO stretch in every peptide unit. • Coupling depends on the conformation • Probe global structure and it’s dynamics. • Require treatment of the local environment Han-sur-Lesse 2009 - Thomas la Cour Jansen
