Heterodyne Two-Dimensional Electronic Spectroscopy

In the past few years, Two-Dimensional (2D)
Spectroscopy has become one of the major tools for
studying molecular dynamics in the condensed phase.
2D Electronic Spectroscopy has unraveled new energy
flow pathways in photosynthetic light harvesting
complexes as well as the dynamics of excitons in
nanostructures. 2D Vibrational Spectroscopy has been
applied to recovering the dynamics of the structural
change in proteins as well as to the structure of
protein aggregates. The molecular information in the
2D Spectroscopy is recovered from detailed analysis
of the 2D spectra. This book links specific features
in the 2D spectra to the physical processes in
molecular systems. The theory involved and the
phase-stabilized heterodyne experimental techniques
are described in details. 2D spectral signatures of
the energy gap fluctuations between the 1st and the
2nd excited states are demonstrated for a generic
3-level system. Heterogeneous dynamics is studied on
the example of J-aggregates, excitonic molecular
aggregates, which perfectly model photosynthetic
light harvesting complexes, protein secondary
structures, as well as protein aggregates.

Igor V. Stiopkin graduated from Moscow Institute of Physics and
Technology with Honors. He did his doctoral work at Columbia
University and at the University of California at Berkeley. His
research interests focus on unraveling dynamics of complex
molecular systems in bulk liquids and at interfaces with
ultrafast nonlinear spectroscopy.
