I'm supposed to calculate the rotational energy levels of NH3, which is a symmetric rotator. The rotational energy levels are determined by the equation(adsbygoogle = window.adsbygoogle || []).push({});

EJK = hcBJ(J+1) + hc(A-B)K^2, where J = 0, 1, 2,..., and K = 0, +/-1, +/-2,..., +/-J

I don't quite get it. Are there a very limited set of rotational energy levels for NH3 that makes it practically possible for me to calculate each one of them, or should I calculate only the, say, first four possible levels? I've looked around for clues in my textbook, but I can't see that there are any.
