【Abstract】 The relation between antimagnetic susceptibility and the area of C-ring symmetric rotators has been calculated.The bigger area of symmetric rotators will cause the rotational energy structure of vibrational spectrabeing to locate in the range of microwave spectra.At the same time,based on the theory of the planar potential well in quantum mechanics and the effect of the delocalization in quantum chemistry,the present work discovers that the bigger the area of C-rings, the lower the energy level interval,and then the rotational constants B will decrease continuously,which make C-rings be propitious to absorb microwave of low frequency bands.The calculated results of quantum mechanics B3P86/6-311G authenticate entirely the theoretic analysis.Moreover,based on the theoretic instruction,the present work has studied the microwave transmissivity of carbon cluster-like absorbing materials AⅡ.The influences of different carbonized temperatures,thickness and material Ⅱ on the transmissivity are reviewed.
【Key words】 antimagnetic susceptibility; rotational spectra; carbon cluster-like absorbing materials; microwave transmissivity;
