    Molecular exclusion surfaces [J. Bentley, J. Phys. Chem. A 104, 9630 (2000)] have been determined for a number of molecules and molecular ions interacting with argon or helium atoms. These surfaces represent the boundaries between the molecules and their environment and have application, for...
