Fluorescent Compounds for Calibration of Excitation and Emission Units of Spectrofluorometer.

Abstract

columns were analyzed grav¡metrically using. 2 -mercaptobenzothiazole (2) (Table I). Preliminary experiments of a similar kind had shown the necessity of leaching the ignited iridium precipitate in boiling 1 to 1 hydrochloric acid, prior to reduction in hydrogen, to eliminate contaminants that follow iridium through the cation exchange columns. This problem has been noted by Tertipis and Beamish (11).

Comparison of chlorophyll far-red and rea fluorescence excitation spectra with photo-synthetic oxygen action spectra for photo-system II in algae

“…The spectrofluorometer was set in the energy mode. System spectral correction was provided by the thermopile method (Argauer & White 1964). The configuration of the thermopile (Kettering Scientific Res.…”

Two dimensional fluorescent sensors: the different dependences of the fluorescence band position and the fluorescence quantum yield of 1,5-diphenyl-3-vinyl-Δ2-pyrazoline upon solvent dipolarity and hydrogen bond acidity

“…The wavelength response function of the emission monochromator -photomultiplier tube combination of the spectrofluorimeter was determined over the range 340-590 nm by the well-known procedure of Lippert et 01. (19) and Argauer and White (20). In particular, we employed 2-naphthol in acetate buffer (pH = 4 3 , quinine sulphate in 0.1 M &So4, and 3-nitrophenyl dimethylamine in hexane:toluene (7:3 v/v) as the fluorescence emission spectral standards.…”
