Vernier Flash Photolysis Spectrometer

Vernier Flash Photolysis Spectrometer product image

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).

Description

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
