The rotational energy levels of the CO molecule are calculated in Example 42.2 and the vibrational-level energy differences are given in Example 42.3. The vibrational and rotational energies are given by Eq. (42.9). Calculate the wave• length of the photon absorbed by CO in each of the following vibration-rotation transitions:
(a) n = 0, l = 1 → n = 1, l = 2;
(b) n = 0, l = 2 → n = 1, l = 1;
(c) n = 0, l = 3 → n = 1, 1 = 2.
