The Kayser ( unit symbol : kayser) is after the German physicist Heinrich Kayser named traditional unit of wavenumber . It was recommended by the Joint Commission for Spectroscopy before 1952 on the basis of a suggestion by William Frederick Meggers , but was not included in the International System of Units . Nevertheless, the unit has long been used in spectroscopy.
other names
Albert Christopher Candler suggested naming the unit Rydberg after the Swedish physicist Johannes Rydberg . Another name proposed in 1951 was Balmer , after the Swiss physicist Johann Jakob Balmer . After some heated discussions, no unit of its own was finally introduced, but cm −1 continued to be used.
1 kayser = 1 cm −1 = 100 m −1
