H2 has a moment of inertia equal to 4.603 x 10-48 kg m2.(adsbygoogle = window.adsbygoogle || []).push({});

1) Calculate its bond length.

2) For the first 3 rotational energy levels, find the

a) l quantum number

b) ml quantum number

c) the degeneracy of each rotational level

d) energy eigenvalues

e) the magnitude of l

Ok so I calculate bond length using the I=mu(reduced mass) * r^2

I get confused when it comes to l. Are the first three rotational energy levels equal to 1,2,3? or 0,1,2? So would l be equivalent to these energy levels and the m will be +/- l?

Where would I find the energy eigenvalues and magnitude of l?

Thanks in advance!
