The nature of the carbon–phosphorus bond in methylidynephosphine

Abstract
Nuclear magnetic resonance parameters have been determined for solutions of HCP, and a 1J(13CH) value of 211 Hz is rationalized in terms of sp hybridization at carbon, leading to a triple bond description of the CP bond; the appearance potential of the HCP+ or DCP+ ions from the parent molecules (11·4 ± 0·3 eV) is close to a theoretical value.
