Résumé :

The ro and rs geometrical parameters of the acetylene molecule in the linear X̃, G̃ and Ĩ electronic states are determined from the Bo rotational constants of several isotopes. The comparison of the internuclear distances shows a lengthening of the C ‐ C and C ‐ H bonds in the excited states compared to the ground state. Copyright © 1980 Wiley‐VCH Verlag GmbH & Co.
