  14. Time Resolved Vibrational Spectroscopy of Chemical Reactions • One narrowband ultrafast IR laser pulse excites vibrational modes in a molecule and is followed by a second broadband infrared pulse, which gives two independent frequency axes and allows the collection of 2D-IR spectra. • Spectra provide direct information on vibrational anharmonicities, energy transfer processes, and molecular structure. http://www.cchem.berkeley.edu/cbhgrp/ LSUM 2013, October 5-7, 2013 | Ankara University Pervin Arıkan| Gazi University Ömer Yavaş | Ankara University

  15. Spectroscopy of the Solid State • Carrier dynamics: • Quantum wells, superlattices, and quantum dots (e.g. • inter- and intra-subband/miniband relaxation, Bloch • oscillations) • Infrared and THz properties: • Electricallydrivenquantum structures (Bloch oscillators • and quantumcascade lasers) • Resonant coherent effects: • High-intensity laser pulses closely resonant with the • intersubband energy can induce coherent phenomena • such as dressed states and Rabi oscillations • Electrondynamics: • Ultrashort IR pulses with controlled phases.

All experiments are planned to start pre-FEL beam LSUM 2013, October 5-7, 2013 | Ankara University Pervin Arıkan| Gazi University Ömer Yavaş | Ankara University

  17. Pump-Probe Method • Pump-probe method enables to follow in real time vibrational motions coupled to electronic transitions. The sample is excited by one pulse train (pump) and the changes it induces in the sample are probed by the second pulse train (probe), which is suitably delayed with respect to the pump. Changes in the order of picosecond can be observed with this method. LSUM 2013, October 5-7, 2013 | Ankara University Pervin Arıkan| Gazi University Ömer Yavaş | Ankara University

  18. Sum Frequency Generation (SFG) Spectroscopy Sum Frequency Generation (SFG) is a nonlinear optical technique used to study the details of molecular structure and dynamics at surfaces and interfaces. SFG has advantages in its ability to be monolayer surface sensitive, ability to be performed in situ (for example aqueous surfaces and in gases), and not causing much damage to the sample surface. This spectroscopy method utilizes SFG, where two light beams mix at a surface and generate an output beam with a frequency equal to the sum of the two input frequencies. From the experiment setup and the output beam, one can deduce the composition, orientation distributions, and some structural information of molecules on a surface.
