Title: attractive–mixed–repulsive classification Long Title: IUPAC Gold Book - attractive–mixed–repulsive classification DOI: 10.1351/goldbook.A00518 Status: current Definition A classification of potential-energy surfaces in which a highly attractive surface is at one extreme and a highly repulsive surface is at the other. The energy release in intermediate cases is referred to as mixed. Related Term - potential-energy surfaces: https://dev.goldbook.iupac.org/terms/view/P04780 Source - PAC, 1996, 68, 149.
