It measures the degree of pairing of electrons in a molecule, with an increasing value as the electron pairing increases. Therefore chemical bonds, core domains and lone pairs can be visualized. \n\nThe EPLF [1] has been designed to describe local electron pairing in molecular systems. \nIt is defined as a scalar function defined in the three-dimensional space and taking \nits values in the [-1,1] range. It is defined as follows:\n\n<math>\n  {\\rm EPLF}(\\vec{r}) = \n  \\frac { d_{\\sigma \\sigma} (\\vec{r})     \n        - d_{\\sigma {\\bar \\sigma}} (\\vec{r}) }\n        { d_{\\sigma \\sigma} (\\vec{r}) \n        + d_{\\sigma {\\bar \\sigma}} (\\vec{r}) }\n</math>\n\nwhere the quantity <math>d_{\\sigma \\sigma} (\\vec{r}) </math> [resp. <math> \nd_{\\sigma {\\bar \\sigma}} (\\vec{r}) </math>] denotes the quantum-mechanical average of the distance between an \nelectron of spin  <math> \\sigma </math> located at <math>\\vec{r}</math> and the closest electron of same spin (resp., of opposite spin <math>\\bar{\\sigma}</math>).\n\nThe mathematical definition of these quantities can be written as\n\n<math>\nd_{\\sigma \\sigma}(\\vec{r}) = \\int \\Psi^2(\\vec{r}_1,\\dots,\\vec{r_N})\n\\left[ \\sum_{i=1}^N \\delta(\\vec{r}-\\vec{r}_i)\n\\min_{j\\neq i;\\sigma_j=\\sigma_i}|\\vec{r}_i - \\vec{r}_j| \\right] d\\vec{r}_1 \\dots d\\vec{r}_N\n</math>\n\n<math>\nd_{\\sigma {\\bar \\sigma}}(\\vec{r}) = \\int \\Psi^2(\\vec{r}_1,\\dots,\\vec{r}_N)\n\\left[ \\sum_{i=1}^N \\delta(\\vec{r}-\\vec{r}_i) \\min_{j\\ne i;\\sigma_j\\neq\\sigma_i}|\\vec{r}_i - \\vec{r}_j| \\right] d\\vec{r}_1 \\dots d\\vec{r}_N\n</math>\n\nwhere <math>\\sigma</math> is the spin (<math>\\alpha</math> or <math>\\beta</math>),\n<math>\\bar{\\sigma}</math> is the spin opposite to <math>\\sigma</math>,\n<math>\\Psi(\\vec{r}_1,\\dots,\\vec{r}_N)</math> is the wave function, and <math>N</math>\nis the number of electrons.\n\nIn a region of space, if the shortest distance separating anti-parallel\nelectrons is smaller than the shortest distance separating electrons of same\nspin, the EPLF takes positive values and indicates pairing of anti-parallel\nelectrons. In contrast, if the shortest distance separating anti-parallel electrons is\nlarger than the shortest distance separating electrons of same spin, the EPLF\ntakes negative values and indicates pairing of parallel electrons (which in practice\nnever happens). If the shortest distance separating anti-parallel\nelectrons is equivalent to the shortest distance separating electrons of same\nspin, the EPLF takes values close to zero and indicates no electron pairing.\n \nThe original formulation of EPLF is extremely easy to compute in the quantum\nMonte Carlo framework. However, it is not possible to compute it analytically due to\nthe presence of the ''min'' function in the definitions of <math> d_{\\sigma\n\\sigma} </math> and <math> d_{\\sigma {\\bar \\sigma}} </math>.\n\n----\n[1] [http://dx.doi.org/10.1063/1.1765098 '''Electron pair localization function, a practical tool to visualize electron localization in molecules from quantum Monte Carlo data''']<br> A.
