Zeeman data are listed for 207 lines of Ru I between 2400 and 5400 A, all of which have been classified. The spectrograms were made at the Massachusetts Institute of Technology and were analyzed there and at the National Bureau of Standards.Harrison and McNally2 published Zeeman data for 450 lines of the first spectrum of ruthenium (Ru I) in 1940. In addition unresolved patterns were measured by McNally for 175 lines, but these have never been published.3 Further Zeeman observations were made in 1949 by Meggers with the Bitter magnet at the Massachusetts Institute of Technology. These plates were measured by Kessler in the course of preparing material for the preceding paper. Zeeman data for 32 additional lines obtained from this last set of observations, together with the unpublished material from McNally’s thesis for 175 lines are listed below.The observations were all made with electrodes of 1 part ruthenium powder mixed with 5 parts of silver powder. The experimental conditions and techniques used are fully described by Harrison and McNally.2The wavelengths (in air) of these lines are given in column 1 of Wavelength Lower level Upper level Source
