Abstract
Cyclopropanecarboxylic acid has been studied by microwave spectroscopy, electron diffraction and ab initio computations at the 4-21G level. The molecule is found to prefer a conformation that has the carbonyl group syn to the cyclopropyl ring. A second conformer is also present with an energy 3-5 kJ mol −1 less stable. This rotamer is found to have the carbonyl group anti to the ring. An accurate structure has been derived making use of electron diffraction and microwave data in a joint analysis
