Welcome to the Center for Chemical and Biophysical Dynamics.
The Center for Chemical and Biochemical Dynamics (CCBD) is a shared facility housed in the Department of Chemistry and Biochemistry at The Ohio State University and has been set up to provide OSU faculty, staff and students as well as external users with access to state-of-the art laser spectroscopy instrumentation for both ground and excited state experiments.
The various instruments are available for direct usage by any trained user or samples can be sent to the manager to run. For the Horiba Fluorolog-3, new users must register and request training through the FOM calendar. For the femtosecond transient absorption (TA) and time-resolved infrared (TRIR) experiments, new users should contact the manager directly.
The Horiba Fluorolog-3 is located in Newman and Wolfrom 0112. It 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 or powder.
The CCBD facility is located in Newman and Wolfrom 0140. 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.
