摘要: A theoretical framework is developed to analyze molecular bond breaking in dynamic force spectroscopy using atomic microscopy. An analytic expression of the observed probability as a function obtained terms relevant physical parameters. The force-ramp mode discussed detail, which gives best extract parameters such potential depth and its width, if set widely different force-loading rates are used. We also show that commonly used Ritchie-Evans model incomplete it only applicable for forces well below maximum permitted by potential. Statistical complications arising from use constant velocity experiments detail.
