Abstract
The microwave spectra of
phosphaethene (methylenephosphine) and five of its isotopic species have been
observed and assigned in the region 5-125 GHz. Rotational constants and moments
of inertia have been determined for 12CH2PH, 13CH2PH,
12CD2PD, 12CD2PH, (Z)-12CHDPH and (E)-12CHDPH. The moments of
inertia have been used to determine the following structural parameters: rP-H= 1.425�; rC-P=
1.671�; rC-H,= 1.082�; <HCP(Z) = 124.5�; <HCP(E)
= 119.1�; <CPH = 95.5�. The dipole moment components have been determined as
�a = 0.7233(7) D and �b =
0.4657(ll) D.
