Facilities Home Tour Our Facilities X-Ray Crystallography Nuclear Magnetic Resonance Electron Paramagnetic Resonance Laser Spectroscopy Muscle Mechanics Basic Sciences Computing Laboratory Optical (Laser Spectroscopy) The Laser Spectroscopy Laboratory in the Division of Structural Biology and Biophysics, is a shared resource (operated as an ISO) that contains instrumentation for time resolved fluorescence (picoseconds to nanoseconds) and phosphorescence (microseconds to milliseconds) experiments. These experiments are used for analyzing protein and lipid dynamics and association. * Fluorescence: ISS K2 Multifrequency Time-Resolved Fluorometer, using a high-power Ar laser. * Phosphorescence: Time resolved detection of emission or absorption following a pulse from a XeCl excimer laser.
