The Russo-Tartaglia-Sciortino model is given by [1] (Eqs. 1-3):

 \Phi_{12} =  \left(\frac{1}{r_{12}}\right)^{m} - \sum_{i=1}^{M_1}\sum_{j=1}^{M_2} \epsilon \exp \left[ -\frac{1}{2}\left( \frac{r_{12}^{ij}}{\alpha}\right)^n \right]

where r_{12} is the distance between the centre of mass of particles 1 and 2, r^{ij}_{12} is the distance between patches i and j on different particles, and M_1 and M_2 are the number of patches of particles 1 and 2 respectively.
