Definition of hyperchromic effect. 1) an. increase in absorption intensity; if structural modification. leads to an increase in the molar extinction coefficient for a particular. chromophoric group it is said to have brought about a hyperchromic. effect.ncrease in absorption intensity; if structural modification. leads to an increase in the molar extinction coefficient for a particular. chromophoric group it is said to have brought about a hyperchromic. effect.
A series of structurally related molecules in a substitution series can also show a hypsochromic shift. Hypsochromic shift is a phenomenon seen in molecular spectra, not atomic spectra-it is thus more common to speak of the movement of the peaks in the spectrum rather than lines.ecause the blue color in the visible spectrum has a shorter wavelength than most other colors, this effect is also commonly called a blue shift. This can occur because of a change in environmental conditions: for example, a change in solvent polarity will result in solvatochromism.
