Chromophore - Wikipedia
A chromophore is a molecule which absorbs light at a particular wavelength and reflects color as a result. Chromophores are commonly referred to as colored molecules for this reason. The word is derived from Ancient Greek χρῶμᾰ (chroma) 'color' and -φόρος (phoros) 'carrier of'.
Chromophore | Molecular Structure, Absorption, Fluorescence
chromophore, a group of atoms and electrons forming part of an organic molecule that causes it to be coloured. Correlations between the structural features of chemical compounds and their colours have been sought since about 1870, when it was noted that quinones and aromatic azo and nitro compounds often are highly coloured and that the colours ...
Chromophores, Auxochromes, Absorption and Intensity shift
Oct 3, 2023 · A chromophore is an atom or group that contributes to the color of a chemical. Molecules absorb some visible spectrum wavelengths while reflecting others. The wavelength reflected by the molecule is what we experience as color.
Chromophore - an overview | ScienceDirect Topics
Chromophores are molecules in a given material that absorb particular wavelengths of visible light, and in doing so confer colour on the material.
What Causes Molecules to Absorb UV and Visible Light
Jan 30, 2023 · Groups in a molecule which absorb light are known as chromophores. The diagram below shows a simple UV-visible absorption spectrum for buta-1,3-diene - a molecule we will talk more about later. Absorbance (on the vertical axis) is …
What is a Chromophore? (with pictures) - AllTheScience
May 21, 2024 · A chromophore is a group of atoms within a molecule which are responsible for the color of the molecule. Chromophores are found in a wide variety of molecules, and can work in several different ways.
Chromophore - an overview | ScienceDirect Topics
In chemical textbooks, a chromophore is a molecule or a group in a molecule that is the ‘carrier of color’ in the visible spectral region. More generally, one chromophore does belong to every absorption band and vice versa. But besides this, the notion is only intuitively defined.
Chromophore Definition & Meaning - Merriam-Webster
The meaning of CHROMOPHORE is a chemical group (such as an azo group) that absorbs light at a specific frequency and so imparts color to a molecule; also : a colored chemical compound.
Chromophore - an overview | ScienceDirect Topics
A chromophore is a substance that absorbs light, either naturally present in the eye or introduced from external sources, such as an exogenous agent. In the eye, chromophores like proteins, melanin, and specific pigments can absorb light and play a …
Chromophore - (Chemical Kinetics) - Vocab, Definition ... - Fiveable
A chromophore is a part of a molecule responsible for its color, which absorbs specific wavelengths of light and reflects others. This absorption of light is crucial in many spectroscopic methods, as it allows researchers to measure kinetic processes by monitoring the changes in absorbance as a reaction progresses.
