Fluorescent studies

Fluorescence Studies. Fluorescence spectra of films on glass plates were obtained with a Perkin-Elmer MPF-3 spectro-fluorimeter. A previously-described phase fluorimeter was utilized for fluorescence lifetime determinations.

In the case of 7-methyl-B[a]A (155) and 7,12-dimethyl-B(a]A (DMBA) (50,55,57,156-158) most of the evidence supports bay region diol epoxide adducts. Thus, fluorescence studies (50,55,56,159), light sensitivity of the adducts (160), and analysis of adducts formed by further oxidations of the 3,4-dihydrodiol all suggest a bay region diol epoxide intermediate (161,162). More recent evidence 

In spite of the heavy atom, compound (32) is sufficiently fluorescent for this to be used as an analytical tool to examine localization and pharmacokinetics. In EMT-6 murine tumors, (32) localizes initially on lysosomes, with selectivity for tumor over surrounding normal tissue, and with evidence for apoptotic cell kill.137 Fluorescence studies using a hamster cheek pouch model show a maximum emission in 2-3 h, with selectivity for the tumor (x 1.5 over normal tissue) after 24 h the photosensitizer is no longer detectable.138 Lutetium texaphyrin (32) has been compared 

Ultrafiltration utilizes membrane filters with small pore sizes ranging from O.OlS t to in order to collect small particles, to separate small particle sizes, or to obtain particle-free solutions for a variety of applications. Membrane filters are characterized by a smallness and uniformity of pore size difficult to achieve with cellulosic filters. They are further characterized by thinness, strength, flexibility, low absorption and adsorption, and a flat surface texture. These properties are useful for a variety of analytical procedures. In the analytical laboratory, ultrafiltration is especially useful for gravimetric analysis, optical microscopy, and X-ray fluorescence studies.

In 1999, the Klemperer group published experimental results from a dispersed fluorescence study of the linear and T-shaped Ar l2(X, v = 0) conformers to obtain information about the X- and B-state potentials of the complex and to gain insight into the photodissociation dynamics in the B electronic state [65]. In carrying out their analysis, they assumed that the linear and T-shaped conformers existed in a thermodynamic equilibrium, with the abundance of the linear conformer being three times that of the T-shaped conformer. In an effort to test the validity of the thermodynamic hypothesis Bastida, et al. [66], performed a
