Abstract

A quantum mechanical model that considers tunneling and inelastic scattering has been applied to explain the hole transfer reaction from a G (Guanine) base to a GGG base cluster through a barrier of Adenine bases, (A)<sub>n</sub> (<em>n</em> = 1-16). For <em>n</em> = 1, the ratio of tunneling to inelastic scattering is about 6, which is sharply decreased to around 0.23 and 5.23 × 10<sup>-8</sup> for <em>n</em> = 4 and 16 respectively, suggesting dominance of inelastic scattering for <em>n</em> ≥ 4. As in experiment, the calculated product yield ratios (P<sub>GGG</sub>) exhibit a strong distance dependence for <em>n</em> < 4, and a weak distance dependence for <em>n</em> ≥ 4. We also predict conditions under which oscillatory or non-oscillatory charge transfer (CT) yield are expected. .
