How do I learn UV/Vis spectroscopy?
For an in-depth introduction to UV/VIS spectroscopy we recommend the “UV/VIS Spectrophotometry – Fundamentals and Applications” guide, which is available here: www.mt.com/uv-vis Many compounds absorb ultraviolet or visible light, a behavior that is described by the Beer-Lambert law.
What is the UV-visible spectroscopy 37 (B)?
