4. The transition between the ground and first excited vibrational levels of the ICl molecule is observed at a wavenumber of 381 cm-1. Given that the vibrational energy levels of a diatomic molecule such as ICl are singly degenerate, determine the relative populations of the ground and first excited vibrational levels at temperature of 400 K.
