Repeat Prob. 15.7 for the gauche and the anti conformers of butane (see Fig. 15.13). Be sure and give the CCCC dihedral angle for each. Comment on the dipole moment values.
In Figure 15.13

In Problem 15.7
Use the CCCBDB (Section 15.1) to find the electronic energy, dipole moment, and equilibrium geometry for the ground electronic state of NH3 given by a HF/6-31G* calculation and by a HF/cc-pVDZ calculation.
