ISOSBESTIC Meaning and
Definition
-
Isosbestic is an adjective used to describe a phenomenon in which two or more chemical compounds or physical species share a common absorption wavelength or point. It refers to a situation where the absorption spectra of these substances intersect at a specific wavelength, resulting in equal absorbance values for each component at that particular point. The term "isosbestic" is derived from the Greek words "iso," meaning equal, and "sbestikos," meaning point of intersection.
In spectroscopy or analytical chemistry, the concept of isosbestic points is widely employed. When two or more substances absorb light at different wavelengths but exhibit an isosbestic point, it suggests that a chemical or physical transformation is occurring without altering the composition of the sample. Consequently, the intensity of light absorbed at this isosbestic point remains constant, irrespective of the concentrations of the individual species.
Isosbestic points are crucial in applications such as photometric analysis, where multiple components may be present and undergoing conversion. By utilizing a wavelength that corresponds to an isosbestic point, researchers can monitor changes in absorbance without the need for lengthy calibration curves or the isolation and separation of individual species. The isosbestic behavior permits more efficient and accurate quantification, as well as the characterization of chemical reactions involving multiple constituents. In summary, isosbestic refers to the equality of absorbance among components at a shared absorption wavelength or point, making it a significant concept in various analytical methods and studies involving mixtures of chemical species.

Etymology of ISOSBESTIC
The word "isosbestic" originated from the field of spectroscopy, specifically from the observation of isosbestic points on a graph. The term is ultimately derived from the combination of two Greek words:
1. "Iso" (ἴσο): Meaning "equal" or "same" in Greek.
2. "Sbestic" (σβεστικός): Originally derived from the Greek word "sbennynai" (σβεννύναι), meaning "to extinguish". In the context of spectroscopy, it refers to the points on a graph where the absorbance of two (or more) substances is equal or at the same level, causing a "quenching" or "extinguishing" effect on the absorbance.
