Its Applications: Uv-vis Spectroscopy And

(Molar Absorptivity): A constant specific to the substance and wavelength. (Path Length): Typically 1 cm, using a standard cuvette. Essential Components

Ultraviolet-Visible (UV-Vis) spectroscopy is a robust analytical technique used to measure how much a substance absorbs or transmits light in the UV (190–400 nm) and visible (400–800 nm) regions . It is a foundational tool in modern laboratories due to its high speed, low cost, and non-destructive nature. 🔬 Core Principle and Instrumentation UV-VIS Spectroscopy and Its Applications

The technique operates on the principle of . When a molecule absorbs UV or visible light, its electrons move from a low-energy ground state to a higher-energy excited state. The Beer-Lambert Law (Molar Absorptivity): A constant specific to the substance
