Chromophore definition hplc
A chromophore is the part of a molecule responsible for its color. The color that is seen by our eyes is the one not absorbed by the reflecting object within a certain wavelength spectrum of visible light. The chromophore is a region in the molecule where the energy difference between two separate molecular orbitals falls within the range of the visible spectrum. Visible light that hits the chromo… WebChromophore Detection Wavelengths Chromophores are light absorbing groups. Their behavior is used to allow the detection of analytes. They have one or more detection …
