Question:

Part A A colorless, odorless gas in a tank needs to be identified. The gas is nitrogen (N2) carbon monoxide (CO) or nitric oxide

Part A
A colorless, odorless gas in a tank needs to be identified.
The gas is nitrogen (N2) carbon monoxide (CO) or
nitric oxide (NO) (Figure 1). White light is passed
through a sample to obtain an absorption spectrum.
Among others, the following wavelengths present dark
bands on the spectrum: ) = 4.2680 pm, 4.2753 pm,
4.2826 um, 4.2972 pm, and 4.3046 um. These
represent transitions from the lowest rotational states.
What photon energies correspond to these wavelengths? Specify your answers to five significant figures.
Note that the speed of light is 2.9979 x 108 m/s and h = 4.1357 x 10-15 eV .s.
Express your answers in electron volts to five significant figures. Enter your answers in
descending order separated by commas.
