Bayram Research Group   

      Experimental Atomic Molecular and Optical Physics              





We are an experimental research group in Atomic, Molecular and Optical Physics (AMO) and particularly interested in coherent interaction of light with matter. Using double or triple resonance excitation of molecular systems we measure the radiative lifetimes of the highly excited molecular energy states. Rovibrationally and time-resolved molecular spectroscopy in conjuntion with the photon counting method is used to measure radiative lifetimes which offers accurate knowledge of the transition dipole moments and thus provide a better understanding of the structure of the excited molecular states and their decay dynamics. Our research projects are supported by the National Science Foundation.
