From linear to folded simply by CH⋅⋅⋅O bonding: A new low-temperature photoelectron spectroscopy apparatus is used to study hydrogen bonding between unactivated alkanes and a carboxylate group. Gaseous linear carboxylates 1, CH3(CH2)nCO2−, assume folded structures 2 at low temperatures by weak CH⋅⋅⋅O hydrogen bonding between the terminal CH3 and CO2− groups for n≥5.
