ULTRAVIOLET SPECTROPHOTOMETRY Meaning and
Definition
-
Ultraviolet spectrophotometry is a scientific technique used to measure the amount of ultraviolet (UV) light absorbed or transmitted by a substance. It involves the use of a spectrophotometer, an instrument that measures the intensity of light at different wavelengths, to investigate the interaction between ultraviolet radiation and a sample.
This analytical method is based on the principle that compounds absorb light at specific wavelengths, known as absorption peaks, which are characteristic of their chemical structure. Ultraviolet spectrophotometry is particularly useful for analyzing organic compounds, such as pharmaceuticals, proteins, and nucleic acids, as well as inorganic substances like transition metal ions.
In practice, a sample is placed in a cuvette or a quartz cell and subjected to a range of UV wavelengths. The spectrophotometer measures the intensity of light before and after it passes through the sample, allowing researchers to determine the fraction of light absorbed. This absorption data is then used to calculate the concentration or purity of the sample, based on the principles of the Beer-Lambert law.
Ultraviolet spectrophotometry has numerous applications across various scientific disciplines, including chemistry, biochemistry, pharmacology, and environmental analysis. It is commonly used for quantitative analysis, identification of unknown substances or impurities, and monitoring chemical reactions.
Overall, ultraviolet spectrophotometry is a powerful and versatile analytical tool that enables researchers to study the absorption properties of materials in the ultraviolet region of the electromagnetic spectrum, providing valuable insights into their composition, structure, and behavior.

Etymology of ULTRAVIOLET SPECTROPHOTOMETRY
The word "ultraviolet spectrophotometry" can be broken down into smaller parts to understand its etymology:1. Ultraviolet: "Ultra-" comes from the Latin word "ultra" meaning "beyond" or "transcending". "Violet" refers to the color that represents shorter wavelengths of light in the visible light spectrum.2. Spectro: This component comes from the word "spectroscopy", which originated from the Latin word "spectron" meaning "specter" or "image". It relates to the study of the interaction between matter and electromagnetic radiation.3. Photo: This prefix comes from the Greek word "phōs" meaning "light". It is commonly used in scientific terms related to light, such as photography or photovoltaic.4. Meter: This suffix originates from the Greek word "metron", which means "measure". It indicates a measurement or device used for measuring.
