Comparison of hydrogen bonds, halogen bonds, CH⋯π interactions, and CX⋯π interactions using high-level ab initio methods

- Accurate potential energy curves for YH⋯O, YBr⋯O, YH⋯π, and YBr⋯π complexes.
- All four of these interaction types can exhibit similar strengths.
- Identity of Y group has strong impact on interaction strength and character.
- Dispersion plays larger role in YH⋯π and YBr⋯π complexes.
