The equilibrium separation of the atoms in H^{35}CI equals 1.27 x 10-10m. Calculate the energy separation between adjacent lines in the rotational-vibrational spectrum

2. Relevant equations

E = (n + 1/2)[STRIKE]h[/STRIKE][itex]\omega[/itex] + [STRIKE]h[/STRIKE]^{2}/ 2I * l(l+1)

I = [itex]\mu[/itex]r_{0}^{2}[itex]\mu[/itex] = m_{1}m_{2}/ m^{1}+ m_{2}

3. The attempt at a solution

I am assuming the above equation for E is what I need to calculate to find the energy separation.

Using the above equation for inertia, I can find a value for it, meaning I can substitute it in.

I was wondering if it was possible for me to get rid of the n+1/2 and the l(l+1) parts from each bit if I assume n = 0 and l = 0?

[itex]\omega[/itex] is obviously the angular momentum, but if I want to calculate that I either need to know the frequency or the force constant, but to calculate either of these, I need the energy. So I'm very confused with what to do!
