INFRARED SPECTROPHOTOMETRY Meaning and
Definition
-
Infrared spectrophotometry is a technique used in analytical chemistry to study the interaction between matter and infrared radiation. It involves measuring the absorption, transmission, and reflection of infrared light by a sample, which can provide valuable information about its chemical composition and molecular structure.
The process of infrared spectrophotometry begins with the generation of an infrared beam that passes through the sample being analyzed. The instrument used for this purpose is called an infrared spectrophotometer. The beam is then absorbed by certain functional groups within the molecules of the sample, causing vibrations or stretching of the chemical bonds. Each functional group absorbs infrared radiation at specific frequencies, leading to the creation of an absorption spectrum.
The absorption spectrum obtained from infrared spectrophotometry can be used to identify and quantify the components present in the sample. The spectrum is typically represented as a graph, with the intensity of absorption plotted against the wavenumber or wavelength of the infrared light. By comparing the observed absorption bands to existing databases or known standards, the chemical composition of the sample can be determined.
Overall, infrared spectrophotometry is a powerful analytical technique that allows scientists to investigate organic and inorganic compounds, as well as determine the presence of certain functional groups within a sample. It finds applications in various fields including pharmaceuticals, environmental analysis, forensic science, and materials science.

Etymology of INFRARED SPECTROPHOTOMETRY
The word "infrared" comes from the Latin prefix "infra", meaning "below", and the English word "red". It was initially coined by the astronomer William Herschel in the early 19th century to describe the invisible form of radiation just beyond the red end of the visible light spectrum.
The term "spectrophotometry" has two main components: "spectro" and "photometry". "Spectro" comes from the Latin word "spectrum", meaning "appearance" or "image". It is derived from the verb "specere", meaning "to look at". "Photometry" is derived from the Greek word "phōs", meaning "light", and the suffix "-metry", which refers to the measurement of something.
