Étude de la distribution de la densité électronique dans les molécules C2, C3 et C4
In: Bulletin de la Classe des sciences, Band 48, Heft 1, S. 1333-1343
The function δ(M), which measures the effect of the bond formation on the density distribution, has been calculated for C2, C3 and C4. The charge build up is found to have an annular character in the first molecule, whereas in the other two it had its maximum on the internuclear axis. This difference is interpreted on the basis of the number of electrons taking part effectively in the formation of the bonds.
