title: Polynomial representation of digital spectrophotometric data of amino acids and proteins.
abstract: It is proposed that experimentally observed spectra of proteins and amino acids be fitted with series of Chebychev polynomials. Such fitted curves are particularly useful in generating noise-free first- and second-derivative spectra. Examples of difference spectra produced from a family of spectra are also given.
