High-Resolution Infrared Study of the Fundamental Bands of Deuteroiodoacetylene
The high-resolution infrared 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) cm-1, D0 = 1.38482(20) x 10(-8) cm-1, and H0 = -1.47(10) x 10(-15) cm-1 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. Copyright 1997 Academic Press. Copyright 1997Academic Press
