A survey has been made of the systems used for the presentation of absorption spectra data in textbooks and journals. An attempt has been made to determine the accepted nomenclature systems, and recommendations have been made where there is some uncertainty as to proper or desirable form of presentation. Examples of data and graphical relation of values have been given to show the relative form of data as presented by different systems.
