The Vernier Flash Photolysis Spectrometer is a simple, user-friendly device for demonstrating the fundamental principles of chemical kinetics and photochemistry to undergraduate chemistry students. It measures the absorption and emission changes over time of a photoexcited sample at a single wavelength, which is determined by a filter (600 nm filter included). Photochemical reactions are very important in many areas of chemistry with applications including photodynamic therapy and solar energy harvesting. These reactions often proceed quickly and, as a result, require fast reaction techniques to analyze. The Vernier Flash Photolysis Spectrometer is a simple, user-friendly transient absorption spectrometer. It is useful for demonstrating the fundamental principles of these types of fast, photo-catalyzed reactions. Some experiment ideas include kinetics of photochemical reactions such as: Excited-state dynamics Triplet-decay analysis Time-resolved phosphorescence Phosphorescence-quenching kinetics Isomerization Reactive free radicals Photocatalysis Spectral coverage:450–750 nm Temporal resolution:100 microseconds Spectral Resolution:Determined by the interference filter used (10 nm with the included 600 nm interference filter) Minimum time window:15 milliseconds Included:Vernier Flash Photolysis SpectrometerAC power supplyOne fluorescence quartz cuvetteUSB cableEmpty filter housing (fits standard size, third party filters: 12.5 mm OD and 9.0 mm ID)600 nm filter (10 nm FWHM) in filter housingUser manualReference ManualFlash Photolysis Spectrometer Software Download
