Reverse Intersystem Crossing from a Triplet State of Rose Bengal

36 LLE Review, Volume 77 Photodynamic therapy is a treatment in which the combination of a dye, light, and oxygen causes photochemically induced cell death. Observations of this effect occurred at least as early as the end of the last century. In 1900, Raab reported that the dye acridine rapidly killed paramecia when exposed to light, but had no effect in the dark.1 This observation quickly ins...

Nanomagnetic control of intersystem crossing.

A theory is presented for how magnetic nanostructures can catalyze intersystem crossing in molecular radical pairs. Magnetic field gradients near physically realistic nanostructures are strong enough to induce a relative reorientation of two electronic spins in <1 ns, overwhelming nuclear hyperfine coupling as a driver of intersystem crossing. Nanomagnetic control of intersystem crossing repres...

Studies of intersystem crossing dynamics in acetylene.

We report a new ab initio study of the acetylene T3 potential energy surface, which clarifies the nature of its energy minimum, and present computed equilibrium geometries and diabatic frequencies. This information enables the computation of harmonic vibrational overlap integrals of T3 vibrational levels with the S1 3nu3 state. The results of this calculation support the interpretation of two l...

Intersystem crossing and characterization of dark states in the pyrimidine nucleobases uracil, thymine, and 1-methylthymine.

The ground and low-lying excited states of the pyrimidine nucleo bases uracil, thymine, and 1-methylthymine have been characterized using ab initio coupled-cluster with approximate doubles (CC2) and a combination of density functional theory (DFT) and semiempirical multireference configuration interaction (MRCI) methods. Intersystem crossing rate constants have been determined perturbationally ...
