Victor Kaufman and John F. Ward, "Newly Measured and Calculated Wavelengths in the Vacuum Ultraviolet Spectrum of Neutral Nitrogen," Appl. Opt. 6, 43-46 (1967)
The NBS 10.7-m vacuum spectrograph was used in the second order to obtain precision measurements of three N i lines at 1492–1495 Å (2p3 2∘–2p23s2P) and four at 1742–1745 Å (2p3 2P∘–2p2 3s2P). By combining these values with other available information on the energy levels of the neutral nitrogen atom, seventy-eight calculated wavelengths of N i from 908 Å to 1745 Å are given with uncertainties of 0.001 Å or less.

Δ1 = 2p23s(2P3/2–2P1/2) splitting. This splitting is given as 83.16 cm−1 in Ref. 2.
Δ2 = 2p3(2P∘3/2–2P∘1/2) splitting.
This number was communicated to the authors by K. B. S. Eriksson in March 1966.
Table II
Levels of the Ground Configuration (2s22p3) of Nitrogen
The values of the intensities from the two sources have been adjusted to be equal for the 1742/5 Å lines.
This is the center of gravity of the unresolved line assuming the theoretical L-S coupling intensities.
The measured value of this line (see Table I) has a smaller uncertainty.
The center of gravity of the measured line is 1742.7289 Å.
The center of gravity of the measured line is 1745.2521 Å.
