The Ã2Π3/2â†�X2Π3/2 laser-excitation spectra of iodoacetylene and deuteroiodoacetylene cations
Abstract
The origin and 3v0(v= 1–3) vibronic bands in the Ã2Π3/2â†�X2Π3/2 laser-excitation spectra of iodo- and deuteroiodo-acetylene cations have been recorded at high resolution (0.04 cm–1) and rotationally analysed. A vibrational analysis of the whole spectrum is made and the inferred spectroscopic information is discussed.
