Abstract:  Infrared spectral data of three different groups of heterocumulenes are reported. A linear dependence of integrated absorption intensities of the vas(X = Y=Z) bands on Hammett substituent constants with a positive slope has been found. On the basis of wavenumbers, half-band widths as well as integrated absorption intensities of the vas(X=Y=Z) bands the structure of the cumulative system of X = Y = Z bonds is discussed.
