Abstract

The reading of wavelengths (or wave numbers) at which maxima occur in ultraviolet spectroscopic analysis on a Cary model 11 recording spectrophotometer can be greatly simplified by the use of an "ultraviolet ruler." The ruler obviates the necessity of having to count wavelengths on recorder paper in which the abscissa is not graduated and on which only a few reference wavelengths are known.
