NISTIR 7458, Paul C. DeRose, October 2007; primary cover title/byline, not the web index title ending Correction. Sections 5–6 describe emission-response and excitation-beam correction. Section 11.2, printed p. 20, Eq. (2), relative methods: absorbance, corrected emission, excitation intensity and refractive index enter the comparison. Section 11.1.1 discusses optically dilute samples; no standard numerical quantum yield adopted without conditions.
