Book Description
Ultrafast spectroscopy is one of the most active areas of research in chemical physics. Understanding the ultrafast behavior of molecules, and influencing it with the help of laser fields may lead to the ultimate goal of controlling the flow and outcome of chemical reactions. This thesis work focuses on the investigation and control of molecular dynamics using time-resolved four-wave mixing (FWM) techniques in gas phase samples. Femtosecond FWM spectroscopy has established itself as a powerful tool to uncover molecular dynamics on ultrafast time scales. The femtosecond time resolution combined with a background-free, highly collimated coherent signal makes the approach unique for studying the dynamics especially under conditions of low concentrations. In gas phase, the elementary reaction paths can be directly probed without the interference of solvent molecules. A comparative study of the molecular dynamics in the gas phase and condensed phase gives a detailed picture on the effect of environment. Utilization of Raman as well as optical resonances in FWM spectroscopy provided high selectivity with respect to the type of molecular dynamics observed in the transient signal. New schemes of FWM spectroscopy, which employs an initial pump pulse along with a fully time resolved FWM process, were devised to monitor also the dynamics of higher lying excited states. A feed back controlled optimization process in a FWM scheme is used to selectively excite or suppress vibrational modes in gas phase and liquid phase of the same molecule. The results of the experiments performed using different FWM techniques to monitor, understand, and also to control diverse aspects of molecular dynamics in different systems are presented and discussed.

Book Description
The book reviews the results of vibration-rotational spectroscopy of molecules obtained recently by combining modern computational methods of quantum chemistry with the new techniques of high-resolution rotational and vibration-rotational spectroscopy. It shows for example that the tunneling vibration-rotational spectroscopy of the van der Waals complexes provides a new look at intermolecular forces while the high precision and sensitivity of the submillimeter-wave and Fourier transform microwave spectroscopy make it possible to study complex rotational spectra of molecules in excited vibrational states. New results of high level ab initio quantum chemical computations of vibrational and rotational energy levels and dipole moment functions of unusual molecules will be discussed together with the recent discovery of clustering of energy levels in asymmetric tops. Group theoretical analysis of floppy molecules, especially the tunneling effects in nonrigid molecules, will also be discussed.
