Some structural relationships between acenes and cyclacenes both Huckel- and Mobius-type and within the same class of compounds were demonstrated by the recursive analysis of their E-pi and I-pi values or the first differences thereof. It was found that the first differences of E-pi and I-pi tend to have certain limit values as the number of benzenoid rings increases in each class of compounds studied.
