London Dispersion and Hydrogen‐Bonding Interactions in Bulky Molecules: The Case of Diadamantyl Ether Complexes

Alkyl groups matter: Complexes between diadamantyl ether (DAE) and water and alcohols with increasing side-chain size have been studied by using rotational spectroscopy. DAE and the clustering molecules interact through an O−H⋅⋅⋅O hydrogen bond and London dispersion (LD) interactions. The H−C⋅⋅⋅H−C LD attractions take place between the alkyl groups of the alcohols and those of DAE. The LD interactions increase with increasing size of the alcohol.
