Since Swalen, Reilly and Kowalewski have successfully explained the high-resolution nuclear magnetic spectra of several ring oxygen compounds and 3-substituted pyridine by the use of the ABX and ABXY as basis and introduced a second-order perturbation, there is reason to believe that multinuclear molecules may also be studied successfully with a similar approach. This paper develops the energy levels and wave-function diagrams of compounds of the types AnBK, ABKn, AnBKL and ABKLn using Corios method of treating the multinuclear wave function as the basic function. In the case of 3-substituted pyridine, the expected condition is not completely and strictly satisfied. But, the specific results are not too different from the direct ones obtained by diagnolization. Hence it has become one of the most important methods of analyzing the wave functions of multinuclei spin systems. Due to the lack of a 60-Mcs high-resolution spectrum, there was no specific numerical check on the results as presented in this paper. Author
