    • 2 axes), the molecule has always at least two enantiomeric forms due to the intrinsic stereogenic center (helicity) of any propeller that provides chirality to the molecule. If the helix adopts a clockwise sense the enantiomer is called Plus (P) whereas if it adopts the opposite sense is called Minus (M). For diradicals 1 and 2 it is straightforward to predict the existence of three stereoisomers, one pair of enantiomers-namely (P,P)-, and (M,M)- and a meso form - namely (M*,P*) - due to the presence of two triphenylmethyl stereogenic centers.

    • 10 Therefore, the two alpha carbon atoms of 1 can be considered in a first approximation as the electron active sites for the electron transfer phenomena. It must also be noticed that as far as intramolecular electron transfer phenomena are concerned, the main distance to be considered is the through-bond distance between the two electron active sites; i.e., the sum of bond lengths corresponding to the conjugated pathway. Such distance, measured from the two radical alpha carbon atoms is 24.1 Å for diradical 1
