Oligomers based on weak hydrogen bond networks: a rotational study of the tetramer of difluoromethane

摘要

We report the rotational spectrum of one conformer of the tetramer of difluoromethane (CH_2F_2)_4 (the first pure rotational spectrum of a tetramer of an asymmetric rotor), and describe the network of weak hydrogen bonds which connect the four subunits.
