Rationale of the rhodamine b method for antimony

Analytica Chimica Acta, 1955
Abstract The chemistry of the colorimetric rhodamine B-benzene extraction method for the determination of antimony is examined and sources of error are considered.

About the microdetermination of thallium with rhodamine B

Fresenius' Zeitschrift für Analytische Chemie, 1965
The spectrophotometric determination of thallium with Rhodamine B as Rhodamine B-thallium(III) tetrabromide using extraction of the complex into benzene was investigated. For the oxidation of thallium(I) ceric sulphate was used. The optimum conditions and interferences of some ions for the determination of microgram amounts of Tl are described.

Spectra of the lowest excited singlet states of rhodamine 6G and rhodamine B

IEEE Journal of Quantum Electronics, 1979
Excited states of laser dyes were generated in solution by an intense 6 ns laser pump pulse tuned to the absorption maximum of the longest wavelength, ground state absorption band. They were interrogated by a shorter, simultaneous, monochromatic pulse of smaller diameter, concentric and collinear with the pump, having a crossed polarization.
