Bond Lengths and Dipole Moments for C=O Compare the calculated bond lengths of your calculated molecules for those saturated and unsaturated ring systems: 1) of same size and 2) of increasing size. Discuss whether or not the trends are consistent with your rationalization of your calculated C= O stretching frequencies. Compare the calculated dipole moments of your calculated molecules. Can you recognize a trend?
