Page "Force spectroscopy" Paragraph 6

Quite often researchers repeat the measurements as a function of the bond loading rate.

The resulting graph of the average rupture force as a function of the loading rate is called the force spectrum and forms the basic dataset for the dynamic force spectroscopy.

In the ideal case of a single sharp energy barrier for the tip-sample interactions the dynamic force spectrum will show a linear increase of the rupture force as function of a logarithm of the loading rate.

The slope of the line is equal to the, where is the distance from the energy minimum to the transition state.
