Using symmetry selection rules it is shown that the S r + TX intersystem crossing (ISC) process in (;:on-rotating) platrar condensed aromatic compounds with lowest states of the X,ZI \* type leads to triplet states with the two unpaired electrons spinning in the molecular plane. Out-of-plane distort
