Systematic Approach for Describing the Geometry of Spectrophotometry

August 1, 2003
Author(s)
E A. Early
In the field of spectrophotometry, the values of the measured quantities depend upon the measurement geometry. Therefore, it is imperative to completely describe the measurement geometry. Many documentary standards specify the geometry for a particular
