Vernier® Flash Photolysis Spectrometer

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.

• Spectral coverage of 450 to 750 nm
• 100 microseconds temporal resolution
• Spectral resolution determined by the interference filter used (10 nm with the included 600 nm interference filter)
• 15 milliseconds minimum time window

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. This 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, and photocatalysis.
