ABSTRACT
Substitution of H and & by (34) and (35) into (33) and, dividing each row of a determinant by leads to.
d e t | ^ y 2 l - A | = 0; t = l ,2 ....... N. (36)
H the normalized form of Huckel theory is used, i.e. if jd is taken as the energy unit and a the zero-energy reference point, ^ = 1 and a = 0, equation (36) becomes.
