Polansky's benzenoid character and the electron content of rings of benzenoid hydrocarbons

, 2005
Summary: In 2004 Balaban and Randić put forward a method to assess the \(\pi\)-electron content EC of rings of benzoid hydrocarbins. Much earlier, in the 1960s, Oskar Polansky conceived and elaborated the concept of benzenoid character \(\rho\) of the same rings.
