Hi,
I have an assignment to derive the two following expressions:
R(J)-P(J)=2B'(2J+1)
R(J-1)-P(J+1)=2B''(2J+1)
where Bis the rotational constant and prime ' stands for upper level and bis '' for lower level.
Bv=Be-α(v+1/2)
using the selection rules (I guess in this case ΔJ=±1) and ΔT=G(v')-G(v'')+F(J')-F(J'') where ΔT is the transition/energy difference
between two energy levels expressed in wavenumbers and F(J)=BJ(J+1)
G(v)=ωe(v+1/2)-ωexe(v+1/2)2.
I don't understand how I'm going to put all of this together and I don't understand what they mean with R(J) and P(J) etc.
Thankful for any help!
