We describe the fluorescence spectral properties of p-bis(O-methylstyryl)benzene (bis-MSB) as a standard for time-resolved measurements of two-photon induced fluorescence. Bis-MSB displays the same single exponential intensity decay in several solvents for one- and two-photon excitation. The anisotropy decay displays the

The electronic structure and one- and two-photon absorption spectra of four fluorophores, p-bis(o-methoxystyryl)benzene (Bis-MSB), coumarin 307, fluorescein and rhodamine B, commonly used as reference compounds for two-photon absorption spectra, have been theoretically calculated and compared with available experimental data. The

Flow cell detectors were developed for simultaneous concentration and scintillation detection of technetium-99 in water. Evaluated flow cell geometries consisted of a coil and a fountain flow cell design; the latter is based on radial solution flow through a resin
