HIGH-RESOLUTION RAMAN SPECTROSCOPY OF GASES: XVIII. PURE ROTATIONAL SPECTRA OF CYCLOPROPANE AND CYCLOPROPANE-d6

Abstract

A high-resolution study of the rotational Raman spectra of cyclopropane and cyclopropane-d₆ has yielded the values 0.6696₂ ± 0.0002₀ cm⁻¹ and 0.4607₉ ± 0.0001₅ cm⁻¹ for their ground-state rotational constants. From these values the C–C internuclear distance is determined to be 1.514 ± 0.002 Å.
