Go to www.nist.gov/pml/data/asd.cfm, click on Levels, enter C I in Spectrum, and click Retrieve Data to find the energy levels of the 2s22p3s configuration of C. Then use the selection rules given in Prob. 11.31 to find the wavenumbers and wavelengths of all allowed transitions between the levels of 2s22p3s and the levels of 2s22p2 given in Prob. 11.31. Check your wavelengths by clicking on Lines instead of Levels.
In Problem 11.31
For the carbon atom, the levels that arise from the 1s22s22p2 configuration are

And the energy levels of the 1s22s2p= configuration are
