Specific Electron Capture. It is now customary to use solvents such as methanol (usually CD3OD) or methyl tetrahydrofuran (MTHF) as solvents if electron-capture by AB is required. These solvents form good glasses at 77 K, and for sufficiently dilute solutions of the substrate, AB, electron ejection occurs overwhelmingly from solvent molecules, so that AB+ centres are not formed. Electrons are fairly mobile, and hence AB radicals are formed provided AB has, effectively, a positive electron affinity. The hole centres, such as CD30D+, are not mobile because proton transfer to surrounding solvent molecules occurs rapidly at all temperatures.
