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: r_P-H= 1·425Å; r_C-P=l·671Å; r_c-H = 1·082 Å; ∠HCP_(Z) = 124·5°; ∠HCP_(E) = 119·1°; ∠CPH = 95.5°. The dipole moment components have been determined as j˜, = 0.7233(7) D and pb = O·4657(11) D.
