Kromoforu
Kromoforu, commonly referred to in English as chromophore, is the part of a molecule that is primarily responsible for color by absorbing light. In chemistry, chromophores are typically associated with conjugated pi-electron systems or certain functional groups that can undergo electronic transitions, such as pi to pi or n to pi transitions, when they interact with visible or near-UV light.
The color arises because the absorbed wavelengths are removed from the spectrum of visible light, and the
Common chromophores include azo groups (-N=N-), carbonyl-containing systems (such as ketones and aldehydes), extended conjugated dienes
In practice, chromophores are central to dyes, pigments, indicators, and various optical applications. They also feature
