Abstract
Abstract The r s and r o structural parameters have been determined for propylene oxide from rotational constants for 16 isotopic species. The heavy-atom ( r o ) parameters are : r (C 1 C 2 ) = 1.470(3), r (C 2 C 3 ) = 1.505(2), r (C 1 O) = 1.441(2), r (C 2 O) = 1.435(3) A, ∠ OC 2 C 2 = 59.1(2), ∠OC 2 C 1 = 59.4(1), ∠C 1 OC 2 = 61.5(2), ∠C 1 C 2 C 3 = 121.7(2), ∠C 2 C 3 = 116.1(2)°. The methyl group torsional angles with the ring are: τ(C 1 C 2 C 3 H 9 ) = 24.7(8) and τ(OC 2 C 3 H 9 ) = −44.0°(5). These parameters agree closely with analogous results for ethylene oxide.
