Cyclopropylcarbonyl fluoride

An investigation of the vibrational spectrum of cyclopropylcarbonyl fluoride was carried out by Durig and coworkers using HF/3-21G theory115. The authors could assign all frequencies of cis and trans conformations and analyse normal modes in terms of potential energy contributions using appropriate symmetry coordinates. The calculated conformational stability and rotational barriers [HF/6-31G(d) and HF/3-21G] were compared with results obtained from the far-infrared spectrum.
