Abstract

Measurement of H/D isotope effects on the¹⁹F resonances of sequentially deuterated 1-n-butyl-3-methylimidazolium hexafluorophosphate and tetrafluoroborate isotopologues reveals the formation of aliphatic C–H⋯X hydrogen bonds between the fluorinated anions and protons along theN-alkyl sidechains of the cations.
