The eigenspectrum of a Möbius graph is a complete inversion of a Hückel graph for odd-numbered monocycles. For even-numbered monocycles, the Coulson-paired levels (xi, - xi) in a Hückel graph become the degenerate levels (x′1, x′1) in a Möbius graph. Here, we present the proof of a general theorem stating that the same eigenspectral relationship is found in a much wider class of graphs. © 1994 John Wiley & Sons, Inc.
