Cyclopropane-d6 has been synthesized from deuterium oxide and magnesium tricarbide in steps giving successively methyl acetylene-d4, propylene-d6, allyl chloride-d5, 3-bromo-1-chloropropane-d6, and cyclopropane-d6. Infrared spectra of cyclopropane and cyclopropane-d6 have been obtained in the spectral region 350 to 3700 cm—1 for the vapor and 650 to 3700 cm—1 for the liquid. Raman spectra, including semi-quantitative depolarization factors, have been determined for the liquid state. The spectroscopic results satisfy the Teller-Redlich product rule for a molecule of D3h symmetry. All active fundamentals in cyclopropane-d6 but one have been directly observed. The inactive fundamentals in both molecules have been located provisionally from overtone assignments. An attempt to determine the molecular geometry from rotational contours of the infrared bands was not successful, but high-resolution work on cyclopropane-d6 shows that the C–C distance is 1.524±0.014 A.
