Calculation of the N nqcc in trifluoromethylcyanoacetylene was made on aa approximate equilibrium molecular structure (~ re)
given by MP2/aug-cc-pVTZ(G03) optimization with empirically corrected
bond lengths. The calculated nqcc is compared with the
experimental value of Kang [1] in Table 1. Structure parameters
are given in Table 2. |
