Abstract : The spin of paramagnetic substances appeared to be the cause of mixing of the singlet-ground-state and excited-triplet-state wave functions during twisting of the molecule about a double bond. The mixing appeared responsible for cis-trans isomerization via the triplet state which is believed to have a lower energy at 90 deg twist than the singlet state.
