  • Nature and Stability of Weak Halogen Bonds in the Gas Phase

    Simultaneous measurements of the collision cross section of water, molecular oxygen, and argon atoms scattered by the same target (CF4 or CCl4) have been performed in the thermal energy range. The experimental results show unambiguously that H2O–CCl4 is ∼0.5 kJ/mol more stable than O2–CCl4 and Ar–CCl4, which is incompatible with a fully noncovalent nature of the interaction.
