## Abstract Strong proton nuclear polarization is produced by the quenching of excited triplet state Rose Bengal molecules by aromatic amines. In secondary amines significant polarization (but no permanent chemical change) is observed in the ring ortho and para protons and in the Nβalkyl Ξ± methylen
## Abstract Paramagnetic nickel(II) complexes which are used as commercial photostabilizers of polyolefins are shown in laser photolysis studies to quench the triplet state of benzophenone in dilute benzene solution. The efficiency of quenching observed is less than that of diamagnetic squareβplana
Quenching of triplet states of carbocyanine dyes by nitroxyl radical has been investigated by the f&b pliotolysis method. Quenching of triplet state carbocyanine dyes with one po~yme#yne chain occurs via enhanced intersystem crossing on exchanse interaction with the radicaf, Quencbiog of tri&t state
Quenching of aromatic excited singlet states (9,10-dimethyl anthracene, 9,10-diphenyl anthracene and perylene) by nitroxyl radical was studied by flash photolysis and fluorimetrically. It is established that the dominant quenching mechanism is enhanced intersystem crossing in the collision complex w
