A. Sketch the potential energy surfaces of HF in the ground state and excited state assuming that the dimensionless displacement is D = 3. Label D on the sketch. 

B. Calculate the “stick spectrum” of the HF HOMO à LUMO transition assuming the T = 0 K approximation and that the vibrational mode is a Franck-Condon active mode.  Make a table shows the individual bands.
