With the growing interest in •his method of analysis, one of the scientific groups might well follow the example of the American Petroleum Institute and undertake a program that would make such spectra available as reference standards. Unless this is done, each labo?atory will first have to establish its own reference library of spectra so that proper identification, research and analysis of these products can be achieved.
