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.
An auxochrome (Greek Î±á½Î¾Î¬Î½ÎµÎ¹Î½ auxÃ¡nein: to increase and ÏÏá¿¶Î¼Î± chrÅma: colour) is a group of atoms attached to a chromophore which modifies the ability of that chromophore to absorb light. They themselves fail to produce the colour; but when present along with the chromophores in an organic compound intensifies the colour of the chromogen.
