Abstract The rotational spectrum of iodoethyne, HCCI, has been observed in the frequency range from 105 to 305 GHz. A sensitive spectrometer system employing source modulation, a harmonic generator millimeterwave source and a liquid helium cooled InSb-detector has been used. The rotational constants and nuclear quadrupole coupling parameters of HCCI have been obtained for the ground state and the

chloride was crucial for the cyclization reaction to occur because neither the iron salt nor diorganyl diselenide alone were able to promote the cyclization. The effects of solvent, temperature, reaction time, and stoichiometry on the efficiency of cyclization reactions were investigated. The standard reaction conditions were compatible with many functional groups in the substrates, such as methyl

The high-resolutioninfrared spectrum of deuterated iodoacetylene has been measured in the region 200-2700 cm-1. In addition to all five fundamentals, the bands 2nu40 and 2nu50 have been identified. The measurements were carried out by using a Fourier transform spectrometer at room temperature with instrumental resolution of about 0.0020 cm-1. The ground state rotational constants B0 = 0.0970742961(72)
