Photochemistry is the study of light-induced chemical reactions and physical processes. Or in other words the chemistry of the effects of light on chemical systems is photochemistry. The pillars of photochemistry are UV/VIS spectroscopy, photochemical reactions in organic chemistry and photosynthesis in biochemistry.
Photochemical reactions and the properties of excited states are also critical in many commercial processes and devices. Photography and xerography are both based upon photochemical processes, while the manufacture of semiconductor chips or the preparation of masks for printing newspapers relies on UV light to destroy molecules in selected regions of polymer masks.
Photochemistry can be classified into these topics:
- Photochemistry.
- Interaction of radiation with matter, difference between thermal and photochemical processes.
- Laws of photochemistry :
+Stark-Einstein law
+Jablonski diagram
- Fluorescence
- Non-radiative processes.
Very informative post.thanks for your information.difference between photochemical and thermal reaction
