39. 11 The plots were practically the same as shown by these authors. The results are not very dependent on the size of the basis set and the presence of the core-electron density. The density maps at MP2/6-311G-(d,p) with and without the core electrons are practically undistinguishable from the MP2/6-31G(d) plots.

42. The NMR magnetic shielding is calculated as derivative of the energy with respect to (i) the magnetic moments of the nuclei and (ii) the external magnetic field. The shielding conctant is given as an asymmetric 3 × 3 tensor. The magnetic susceptibility is calculated as second derivative of the energy with respect to the external field. The result is a symmetric 3 × 3 tensor
43. π occupancy and less positive partial charge of Ge than Si can be explained by the electronegativities. Ge is more electronegative (2.0) than Si (1.7).

47. Figure 1 shows the cisoid structures of 3 and 4. The energy calculations predict that the cisoid form of 3 is marginally more stable than the transoid form, while the opposite holds for 4. The X-ray structure analyses of derivatives of 3 and 4 show the cisoid forms (A. J. Arduengo, personal communication to G.F.). The reaction energies for reactions 1 and 2 are calculated with respect to the more stable isomers. resepctively.
