Chromophore and chromogen
WebFRET happens while the chromophore’s absorption spectrum and the fluorophore’s emission spectrum overlap. The following conditions have a major impact on the FRET’s effectiveness: (i) the distance (r) should be between 2 and 8 nm for energy transfer, (ii) there is a large overlap of the emission spectrum of biomolecules (donors) with the ... WebMay 5, 2024 · Chromophore. It is a covalently unsaturated group which is responsible for absorption of UV or visible radiation and may or may not impact in colour to the compound. A compound which contains chromophore it is called chromogen. In unsaturated linkage such as -c=c- ,-N=N-, the π electron are loosely bound.
