Molecular switching with nonexponential relaxation patterns: a random walk approach.
The transition from an initial, locally stable configuration to a globally stable state in molecular switches is investigated in terms of a random walk model, effectively taking the reaction pathway through a potentially rugged energy landscape into account. Exponential and nonexponential scenarios are discussed and the implications on measurable quantities are explored.
