โฆ Synopsis
Intersystem
crossing in molecular pairs IS examined in relatron to the structure oi the pair. Simple rclationshlps are derived which differ from previously reported ones by the inclusion of the vrbronic nature of intcrcy\tcm cro\ring.

Singlet-triplet intersystem crossing in methylene is considered as a two step process: (a) reversible intramolecular equilibration of singlet and triplet species. and @) collisional deactivation of the vibrationally excited triplet state. The overall process is predicted to be bimolecular. in ngree
A temperature dependent intersystem crossing rate is observed below ca. 170ยฐK for anthracene in methyl tetrahydrofuran. From the temperature dependence of the 0.0 bands in absorption and emission, this is interpreted as being due to slow lattice relaxation in the excited singlet state.
could be obtained from the image by fitting the measured data to this equation. The inset in Figure 3 is a plot of the angle between the (001) normal and the grain boundary plane as a function of distance from the boundary for two different regions of the nanocrystal shown. As can be seen in the fig
