Main Laboratories and Facilities Equipment

(6C-048, Ramachandra R. Dasari)

The CW Raman spectroscopy laboratory is a multi-user facility that contains instrumentation for visible/NIR Raman as well as UV resonance studies. Research projects in the visible Raman laboratory include the resonance Raman spectroscopy of carbon nanotubes, characterization of rhenium clusters for possible use as oxygen sensors, studies of the reaction-induced structural changes in the methane monooxygenase enzyme system, and investigation of the structural properties of left-handed Z-DNA. UV resonance Raman studies include detection of micro-organisms and their toxins, and detection of bio-aerosols on surfaces.
