The constitutions of atrovenetin and of some related herqueinone derivatives
Abstract Deoxy nor herqueinone and atrovenetin have been shown to be identical. On the basis of spectral evidence these compounds, and related substances, have been characterised as substitutedExpand
Photophysics of polycyclic aromatic hydrocarbons adsorbed on silica gel surfaces. 3. Fluorescence quantum yields and radiative decay rate constants derived from lifetime distributions
The fluorescence quantum yields of six polycyclic aromatic hydrocarbons (PAHs) adsorbed on both hydroxylated and highly dehydroxylated silica gel surfaces have been measured, using a diffuseExpand

Surface photochemistry: decomposition of azobis(isobutyronitrile) on dry silica gel
Generation de paires radicalaires par photolyse d'AIBN adsorbe sur une pâte benzene-gel de silice sec. Formation de tetramethylsuccinodinitrile et de ceteneimine. Mecanismes
Publisher Summary This chapter focuses on photochemistry of the solid state. The study of photochemistry of solids is still at the phenomenological stage, and interpretations of experimental resultsExpand
Distributions of fluorescence lifetimes: consequences for the photophysics of molecules adsorbed on surfaces
Abstract The effect of distributions of lifetimes on the recovered fluorescence decay parameters is examined by model calculations. The most notable results are that only two lifetimes are necessaryExpand
