WebbCircular dichroism (CD), measured as a function of wavelength, is the difference in absorbance of left-handed circularly polarised (L-CP) light and right-handed circularly polarised (R-CP) light. This difference can be detected when a chiral molecule contains one or more light-absorbing groups—so-called chiral chromophores. WebbIn nuclear physics, the chiral model, introduced by Feza Gürsey in 1960, is a phenomenological model describing effective interactions of mesons in the chiral limit (where the masses of the quarks go to zero), but without necessarily mentioning quarks at all.
