The natural vibration frequency of a hydrogen molecule is equal to 8.25. 1014 s-1, the distance between the nuclei is 74 pm. Find the ratio of the number of these molecules at the first excited vibrational level (v = t) to the number of molecules at the first excited rotational level (J = t) at a temperature T = 875 K. It should be remembered that the degeneracy of rotational levels is equal to 2J + t.
