Notes:
Radio frequency spectroscopy has been carried out on molecular beams of chloroacetylene to yield Stark and chlorine hyperfine properties for the ground and excited C–H stretching vibrational states. For HCC35Cl v=0, μ=0.440 079(1) D, eQq=−79 733.59(4) kHz, and CCl=1.412(4) kHz. For HCC35Cl v=1, μ=0.462 792(1) D, eQq=−79 744.59(5) kHz, and CCl=1.398(3) kHz. For HCC37Cl v=0, μ=0.439 954(1) D, eQq=−62 839.68(9) kHz, and CCl=1.142(6) kHz. For HCC37Cl v=1, μ=0.462 778(1) D, eQq=−62 848.64(10) kHz, and CCl=1.127(8) kHz. The above results are for J=1 levels, while J=1 and J=2 Stark data for the ground state were combined to give an electric polarizability anisotropy, α(parallel)–α⊥=3.87(2) A(ring)3.
