Methyl Alcohol. II. Molecular Structure

Abstract

From the moments of inertia of six different isotopic species of methyl alcohol as obtained from the J=0→1 rotational lines a complete structural determination of methyl alcohol has been made. The structural parameters so obtained are the following : d_OH=0.956±0.015 A, d_CO=1.427±0.007 A, d_CH=1.096 ±0.010 A, ∠HCH=109°2′±45′, ∠COH=108°52′±2°, and the distance of the oxygen atom from the symmetry axis of the CH₃ group=0.083±0.005 A.
