The force constants for the diatomic molecules CO and HI are 1860 N/m and 320 N/m respectively.

Plot the potential energy curves for these two in a way that highlights their differences (i.e. on a single graph).

Calculate the frequency of motion for both molecules (does this result surprise you?).

Calculate the wavelength of light needed to excite these molecules from their vibrational ground states (v=0) to their vibrational first excited states (v=1).
