Glossary of Terms, Acronyms, and Symbols

The agreement between the measured quantity and the true value. The difference is due to systematic uncertainties, as opposed to random uncertainties that define precision. 

Pre-exponential term for rate constants. Subscript 1 stands for attachment, —1 detachment, 2 dissociation, D recombination of electrons, N recombination of anions, ET electron transfer of ions, —ET reverse of electron transfer. 

Adiabatic electron affinity, energy difference between the ground state of the anion and the most stable state of the neutral molecule. A particular semi-empirical self-consistent field calculation. It stands for Austin Model-1. 

Exponential constant in the Morse potential function. With p as the reduced mass (1 = ve (27i2 i//J(, pG])1.  

Constant relating the energy for a charge transfer absorption maximum to the electron affinity of the acceptor and the ionization potential of the donor. See equation 2.23.
