We have recently shown that fhe photodlssociation of the photodtme~ of 9-meth},~~thracene (MA,) [ I] and of anthracene (A$ [2] takes place predomrnant-Iy from an electron~callp elcrted singlet state at higher temperatures and e\clusl\ely from an excited rnplet state below 170 K. In the singlet state

The reaction pathways for CH(3)COCH(2)OH (hydroxyacetone) photodissociation on the low-lying electronic states have been studied with use of the CASSCF energy gradient techniques. The S(0)/S(1) and S(1)/T(1) intersection points were determined by the state-average CASSCF method. Two main reaction pa
The ultraviolet spectrum of di@enzo[a]anthracene) has been measured. It is essentially a naphthalenetype spectrum showing that the bonds between the two monomers are formed at the carbons 7 and 12 which become tetrahedral.
## Abstract Slow initiation from the bridgehead radical in atom transfer radical polymerization (ATRP) reactions initiated by 9βbromoanthracene photodimers leads to polymers' products possessing high PDI values and higher than expected $\overline M \_{\rm n}$ values. We report here the effects of c
