Abstract:	The molecule 1-phenylphosphaethyne, C₆H₅CP, was detected by microwave spectroscopy when Ph(Me₃Si)CPCl was pyrolyzed in the gas phase at 750°C. Asymmetric rotor transitions between 26.5 and 40 GHz with J = 16 to 22 were analyzed to yield A₀ = 5669.044(72), B₀ = 933.79209(71), and C₀ = 801.59279(75). These data indicate that the bond length r(CC) between the ring and CP group carbon atom is 1.467 Å.
