Abstract
Abstract : The pressure dependence of the fluorescence intensity of 9-anthraldehyde, 9-acetylanthracene and 9-benzoylanthracene was investigated. It was observed that for each of these compounds the intensity of fluorescence increased remarkably as the external pressure was raised. In each case the enrgy of the fluorescent transiton decreased with increasing pressure leading to a large red shift in the mission spectrum. These data are interpreted to indicate that a change in the energy separating the lowest excited singlet and upper triplet energy levels occur when these compounds are subjected to high pressure.
