✦ Synopsis

The high-resolution infrared spectrum of deuterated iodoacetylene has been measured in the region 200-2700 cm 01 . In addition to all five fundamentals, the bands 2n 0 4 and 2n 0 5 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 01 . The ground state rotational constants B 0 Å 0.0970742961(72) cm 01 , D 0 Å 1.38482(20) 1 10 08 cm 01 , and H 0 Å 01.47(10) 1 10 015 cm 01 have been determined by combining 462 ground state combination differences from the same bands mentioned above with accurate MW data from the literature. In addition, the molecular constants for all the fundamental levels have been obtained.
