Poor detection limits of two-photon excited fluorescence in cylindrical capillaries are attributed to photothermal expansion and beam astigmatism. Photothermal expansion is demonstrated for excitation in a 1 cm cell and is inferred for the larger dia

Several common aminopeptidase probes are examined for the strength of two-photon excited fluorescence. The fluorophores 4-methoxy-β-naphthylamine and 7-amino-4-methylcoumarin have limits of detection of 930 pM and 200 pM, respectively. The coumarin

Dispersed fluorescence (DF) spectroscopy is used to explore the rovibrational structure of highly excited S0 formaldehyde (H2CO). A narrowband laser excites formaldehyde molecules to a single S1 rovibronic quantum state, and the resulting fluorescenc

Trace-level impurities, such as those found in organic solvents and aqueous buffer solutions, are known to have little contribution to the two-photon excited fluorescence blank. Previously, the major source of interference in 90° fluorescence detect
