A periodic table for benzenoid hydrocarbons

Abstract

The formulas for all benzenoid hydrocarbons are found in Table PAH6 which has x,y-coordinates of (d _s , N _Ic). Recursive construction of this table was accomplished using an aufbau principle. This table complies to a sextet rule analogous to the octet rule for the periodic table of elements, and d _s is analogous to the outer-shell electronic configuration and N _Ic is analogous to the principle quantum number associated with the periodic table of elements. The aufbau principle and the excised internal structure and strictly pericondensed concepts were evolved in conjunction with the formula periodic table for benzenoid hydrocarbons and represent new ideas formulated by this author. These fundamentals led to the first examples of enumeration of the strictly peri-condensed, non-Kekulean, and total resonant sextet benzenoid groups and has lead to the identification of many topological properties characteristic of benzenoids.
