✦ Synopsis

The hydrogen-bonded dimer between methylenecyclopropane and HF was observed and its rotational spectrum measured with a pulsed-nozzle Fourier-transform microwave spectrometer. Simultaneous analysis of the spectroscopic constants of HF and DF species of the dimer shows that the acid is attached in a T-type configuration to the double bond of methylenecyclopropane in, or near to, the ~ mirror plane that bisects the ring. The tilt of the HF moiety in this plane towards the ring can be included by ascribing a departure from linearity of 12 ° to the hydrogen bond.
