Density-of-state assumptions

We shall refer to these as the density-of-state assumptions. In the present treatment we consider only the one-electron transfer reaction ... 

When E /l < -1.5 or E /l > 1.5, then /P = 1.00 or k /P = 1.00 [see Eq. (11)] and therefore become independent of the values of E or 2 and therefore independent of temperature. When the limiting conditions are not met, the values of k /P and k /P are temperature dependent (details of that behavior will be explored in the next section). This limiting condition is a direct consequence of the aforementioned density-of-state assumptions, i.e., that the density of states is independent... 

Electron-transfer kinetics studied using SAMs self-assembled on a variety of noble metals in addition to gold Such studies will address issues associated with the density-of-states assumptions described in Sec. III.A [93] and will probe how the different orbitals of these metals contribute to the overall electronic coupling [116] as the coupling gets stronger (and the electron-transfer rate constant gets faster) with shorter or more effective (e.g., unsaturated) tethers.
