Abstract
A spectrophotometric method for determining the concentration of chromium in oriented and unoriented single ruby crystals is described. It makes use of the absorption coefficients for the blue and green bands and for the red lines at ∼300°K. The coefficients are based on concentration data obtained by three independent methods.Keywords
