Résumé : Improved sets of data have been recorded and analyzed in order to study the bending rovibrational energy levels of C2D2, in the regions of the ν5-ν4 difference band (FIR) and of the ν5 fundamental band (IR). A matrix model is setup to deal with a Darling-Dennison coupling between sets of bending levels as well as with the usual l-type resonances. A simultaneous fit of the new data together with earlier microwave measurements produces an extended set of very accurate parameters, including for the first time in C2D2 s 45 and qtk. © 1991 American Institute of Physics.
