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
2023年10月3日 · 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. The energy difference between two distinct chemical orbitals in a chromophore falls within the visible spectrum region.
Define and exemplify chromophores - PharmaTutor
2016年10月19日 · (a) CHROMOPHORE: The term chromophore was previously used to denote a functional group of some other structural feature of which gives a color to compound. For example- Nitro group is a chromophore because its presence in a …
What is a Chromophore? (with pictures) - AllTheScience
2024年5月21日 · 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 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.
What are chromophores? - BYJU'S
The chromophore is a component of the molecule in which the energy difference between two molecular orbitals is within the range of the visible spectrum. Visible light that strikes the chromophore can be absorbed by stimulating an electron from its ground state to an excited state.
Chromophore - Simple English Wikipedia, the free encyclopedia
A chromophore is the part of a molecule responsible for its colour. [1] The colour is caused when a molecule absorbs certain wavelengths of visible light. It transmits or reflects only other wavelengths, which causes the colour we see.
What are Chromophores and Chromophoric Shifts? - Lab …
2015年5月18日 · A chromophore has a functional group present in a molecule that is capable of electronic transitions in the UV – VIS spectral range resulting in colour of a compound. Commonly three types of compounds show colour characteristics, namely, organic, inorganic and complex forming compounds resulting from charge transfer between metals and ligands.
Chemistry: What's a Chromophore? - Quirky Science
One online definition of chromophore is “an atom or group whose presence is responsible for the color of a compound.” Although one may think of a chromophore that includes a metal atom such as copper, nickel, or cobalt, in organic chemistry a chromophore is more likely to consist of a collection of carbon-carbon multiple bonds, perhaps with ...
