An auxochrome is a functional group of atoms with one or more lone pairs of electrons when attached to a chromophore, alters both the wavelength and intensity of absorption. If these groups are in direct conjugation with the pi -system of the chromophore, they may increase the wavelength at which the light is absorbed and as a result intensify ...
The color that is seen by our eyes is that of the light not absorbed by the reflecting object within a certain wavelength spectrum of visible light. The chromophore indicates a region in the molecule where the energy difference between two separate molecular orbitals falls within the range of the visible spectrum (or in informal contexts, the ...
A rainbow is a decomposition of white light into all of the spectral colors. Laser beams are monochromatic light, thereby exhibiting spectral colors. A spectral color is a color that is evoked by monochromatic light, i.e. either a spectral line with a single wavelength or frequency of light in the visible spectrum, or a relatively narrow spectral band (e.g. lasers).
In spectroscopy, bathochromic shift (from Greek βαθύς (bathys) 'deep' and χρῶμα (chrōma) 'color'; hence less common alternate spelling "bathychromic") is a change of spectral band position in the absorption, reflectance, transmittance, or emission spectrum of a molecule to a longer wavelength (lower frequency).

It takes all the colors of the rainbow for us to see it that way. It happens because of something called the Rayleigh effect, or Rayleigh scattering, named after a British scientist who first ...
The color of chemicals is a physical property of chemicals that in most cases comes from the excitation of electrons due to an absorption of energy performed by the chemical. The study of chemical structure by means of energy absorption and release is generally referred to as spectroscopy .
Meghan Markle's lifestyle brand is facing major hiccups leading up to its launch. As Ever, originally known as American Riviera Orchard, will coincide with the release of "With Love, Meghan."
The earthiness of the wild rice pairs beautifully with the meaty mushrooms, while fresh spinach adds a burst of color and nutrients in this casserole. It’s the perfect balance of texture and ...
