Since they do not contain chromophoric
groups, polyethylene and polypropylene do not absorb UV light above 220 nm (0.
spectral shape of absorbing chromophoric
dissolved organic matter.
The relative contributions of chromophoric
dissolved organic matter (CDOM) and chl-a to the attenuation of underwater radiation in the water column are shown in Fig.
2+] The molecule contains coelenterazine-2-hydroperoxide in its hydrophobic core cavity, as the chromophoric
ligand which decomposes into coelenteramide and carbon dioxide accompanied by the emission of blue light.
Additionally, in the chemistry it is known that many oxidizing agents (such as NOx) react with phenolic antioxidants to form quinone structures, which are chromophoric
It is known that Ellman's reagent reacts with cysteine to form Ellman's anion, which is chromophoric
, giving it an intense yellow hue.
The behavior of the chromophoric
dye was investigated as it relates to layer ordering, dye aggregation, and film morphology.
Precolumn labeling of lipoproteins was not considered a viable alternative, because incorporation of a chromophoric
or fluorescent probe into the LDL particle may lead to an increase in size.
Brightness gain is achieved by the attack of these perhydroxyl anions on light absorbing chromophoric
groups of lignin and cellulose (carbonyl and conjugated carbonyl groups and quinones).
These are again chromophoric
materials which are to blame for polyurethanes turning brown in sunlight.
It means that interaction of radiation lead to the breakdown of coloring chromophoric
azo group and new products were formed via degradation.
In the first group, the UV radiation changes the chemical structure of the polymer inducing chromophoric
groups and such process is not accompanied by scission of the backbone of the polymer chain.
