Heat denaturation of DNA, also called melting, causes the double helix structure to unwind to form single stranded DNA. When DNA in solution is heated above its melting temperature (usually more than 80 °C), the double-stranded DNA unwinds to form single-stranded DNA. The bases become unstacked and can thus absorb more light. In their native state, the bases of DNA absorb light in the 260-nm wavelength region. When the bases become unstacked, the wavelength of … WebHyperchromic Effect. An effect which leads to an increase in absorption intensity ε max is called hyperchromic effect (Fig. 2.5). The introduction of an auxochrome usually causes hyperchromic shift. For example, benzene shows B-band at 256 nm, ε max 200, whereas aniline shows B-band at 280 nm, ε max 1430. The increase of 1230 in the value ε max

Web9 feb. 2024 · At pH 4 and 5, a bathochromic shift was observed (5 and 30–40 nm, respectively), with a marked hyperchromic effect at pH 5 (up to 272% variation in A max). These bathochromic and hyperchromic shifts are indicators of the anthocyanin–metal chelate formation (Trouillas et al. 2016).
