Abstract

We have gathered information on the vibrational energy states in the ground electronic state of three isotopomers of acetylene $(^{12}C_{2}H_{2}, ^{12}C_{2}D_{2}, ^{13}C_{2}H_{2})$: spectroscopic constants (vibrational frequencies and anharmonicities, geometrical structure, vibration-rotation interaction parameters), observed vibrational energy states and complete sets of predicted vibrational energies and predicted principal rotational constants $B_{v}$ for states of $^{12}C_{2}H_{2}, ^{12}C_{2}D_{2}$ and $^{13}C_{2}H_{2}$ up to 15000, 10000 and $12000 cm^{-1}$ respectively. Statistical parameters (partition functions and integrated number of states) deduced from these predicted spectroscopic data are also provided for the three isotopomers.
