A colorless, odorless gas in a tank needs to be identified. The gas is nitrogen (N2), carbon monoxide (CO), or ni- tric oxide (NO). (See Fig. P42.52.) White light is passed through a sample to obtain an absorption spectrum. Among others, the following wavelengths present dark bands on the spectrum: λ=4.2680 μm, 4.2753 μm, 4.2826 μm, 4.2972 μm, and 4.3046 μm These represent transitions from the lowest rotational states. (a) What photon energies correspond to these wavelengths? Specify your answer
