When a hydrogenatom is abstracted from the methyl group, the cyclopropane ring of the radical produced opens up in a fast and irreversible step. This provides a verification that a source of pumping impacts the hydrogenatom excited state populations. It is initiated by free-radical attack upon a lipid, resulting in the removal of a hydrogenatom from a methylene group adjacent to a double bond. Of course, quantum mechanics originated from the discovery of a fundamental (and unexpected) discretisation of the light absorption or emission spectra of atoms (specifically, the hydrogenatom). Kepler motion and the hydrogenatom are perfectly well understood, and represent central chapters in any textbook on classical or quantum mechanics. In this reaction a hydrogenatom is removed from the alkane, then replaced by a halogen atom by reaction with a diatomic halogen molecule.
