Biphenyl in a cooled alcoholic solution shows structured TT absorption bands, weak in the visible and strong in the UV with a maximum at 3'7OOA and en Er= 50 000 litre mole-1 cm-I. Calculations using the PPP SCF method with a large configuration interaction are done using a planar model. The influen
Triplet-triplet absorption of biphenylene was sensitized by naphthalene. A band is observed at 29 500 cm-l and is assigned to a predicted 3B& + 3B& transition. Triplet biphenylene has a lifetime of 100 psec in solution. Nonradiative processes are thought to affect mainly the first singlet state of b
Transient aburption bands are observed with naphtbakne in solution at 3200-3400 A. in the nme region a~ in the gas phase. It is shown that they do not belong to the naphthalene TT spectrum. Weak and structured 'IT bands are observed between 4300 and 6500 A with methyl derivatives as well as with nap
