Special Seminar: Fundamental aspects and spectroscopic applications of resonantly driven molecular rotation

Fundamental aspects and spectroscopic applications of resonantly driven molecular rotation

Recent advents of intense terahertz field generation have paved the way for nonlinear spectroscopy and coherent control in this unique region of the electromagnetic spectrum. Sub-picosecond terahertz fields resonantly interact with many rotational states simultaneously, and result in repetitive molecular orientation. I will present the fundamental aspects of terahertz induced molecular rotations and its spectroscopic applications, and focus on our recent observation of non-continuous decay profiles of excited rotational populations – a general phenomenon that is revealed in a uniquely pictorial way in a multilevel rotational system.
