Molecular structure of iodoacetylene

The pure rotational spectra of iodoacetylene and its [1- 13C]-, [2- 13C]-, and [D]-isotopomers have been assigned. From the set of four rotational constants obtained, the r 0-structure and the partial r s-structure of the ethynyl moiety have been determined. From the hyperfine structures the nuclear...

Summary:The pure rotational spectra of iodoacetylene and its [1- 13C]-, [2- 13C]-, and [D]-isotopomers have been assigned. From the set of four rotational constants obtained, the r 0-structure and the partial r s-structure of the ethynyl moiety have been determined. From the hyperfine structures the nuclear quadrupole and spin-rotation coupling constants of iodine have also been measured.
