Kayser, the cgs unit of wavenumber. One kayser simply means one per centimeter (typically the quantity being counted is a cycle). One kayser is also synonymous with a reciprocal centimeter or inverse centimeter. The unit honors Heinrich Kayser who compiled a giant atlas of chemical spectra [1]. The unit is historically notated with the symbol K. However this notation conflicts with the internationally accepted SI symbol for kelvin which is also the letter K. For this reason, NIST recommends that use of the letter K as a symbol for 1 cm-1 (1 kayser) should be discontinued [2].
