摘要

Thermally activated barrier crossing in the presence of an increasing load can reveal kinetic rate constants and energy barrier parameters when repeated over a range of loading rates. Here we derive a model of the mean escape force for all relevant loading rates-the complete force spectrum. Two well-known approximations emerge as limiting cases, one of which confirms predictions that single-barrier spectra should converge to a phenomenological description in the slow loading limit.
