✦ Synopsis

SJXctrrr zmd triplet lifcrimes of ;mthraquinonc and a-llsio~cnoanthnquinones were studied in EPA at' 77 K. 11 is sup~cstcd that the emitting stms of a-halogcno3nthraquinones arc the lowest triplet statesand that halogen subnhmion ;]I rhc Q position(s) in antimn~uinonc dfects the electronic configuration of the lowest triplet stzxtcs and their life-Iinlcs.

The phosphorescence, 3L,-3Ka absorption, and 3La-3Ca absorption spectra of anthracenedto in polymethylmethacryIate have been observed at pressures as great as 25 kbar at room temperature. These results with earlier measurements of the pressure dependence of the '4 absorption spectrum confirm that t

From measurements of phosphorescence and triplet-triplet absorption spectra of the title compounds, it is concluded that their lowest triplet states have a RL\* or mixed mr\*-xx\* character with relatively short lifetimes. This unusual character may be caused by distortion of the geometrical structu
