Abstract
The present method of processing spectral data calculates the first to fourth derivative spectra of an original spectrum with respect to the wavenumber and creates a two-dimensional representation by plotting coordinates consisting of the derivative values of some order as their abscissas and the original spectral values or derivative values of another order different from that order as their ordinates. In this two-dimensional plotting, maximal points, minimal points, maximal slope points (inflection points) and the like are clearly represented, so that a great amount of accurate feature information about the analyzed object can be easily obtained.
