The Center for Chemical and Biophysical Dynamics (CCBD) has been set up to provide OSU faculty, staff and students as well as external users with access to state-of-the art femtosecond laser spectroscopy instrumentation. Users are able to complete training to run their samples or samples can be sent to the manager to be run. The CCBD has the equipment necessary to measure broadband transient absorption (TA) and time resolved infrared (TRIR) on femtosecond time scale. We are also in the process of setting up a femtosecond stimulated Raman spectroscopy  (FSRS) system. These experiments can measure how the excited state of a molecule can decay back to the ground state on the femtosecond to 4.0-nanosecond time scale. Probing detection is setup to be transmissive, so samples must be transparent, either liquid or film.

Also available is a Horiba Fluorolog-3 that can measure excitation and emission spectra from 250-1000 nm. Accessories include a set up for time correlated single photon counting (TCSPC) with diodes at 280 and 450 nm and an integrating sphere.  This system can measure liquid, film, solid and powder.  More information available here.
