A Di-Dj plotting method using derivative pairs with different order ( and derivatives) has been proposed as a powerful method of representation of spectral waveform. The principle of the method is explained and some examples of its applications are given to demonstrate the usefulness of the method in the spectral analysis. As the basis of spectral profile analysis. It is explained about the effects of plotting the correlations of derivatives of different order,—first vs. second and third vs. fourth—to separate adjacent bands. Next, the contours of Di-Dj plots created by the Lorentzian function is illustrated. Third, it is shown how the method can be used to determine the presence of an underlying band and how to extract the individual bands from an overlapping peak.
