Circularly polarised emission spectroscopy, otherwise known as circularly polarised luminescence, detects the partial circular polarisation of light emitted from excited chiral molecules and is therefore complementary to circular dichroism spectroscopy. It provides a means of probing both the structure and behaviour of excited states of chiral molecules and of their processes of excitation. Moreover, in certain cases, even racemic mixtures of enantiomeric molecules can be studied by preferentially exciting a particular enatiomer with incident circularly polarised light.
