Abstract
We expand on the comprehensive study of hyperfine structure (HFS) in Mn II conducted by
Holt et al. (1999) by verifying hyperfine magnetic dipole constants (A) for 20 levels previously
measured by Holt et al. (1999) and deriving A constants for 47 previously unstudied levels. The
HFS patterns were measured in archival spectra from Fourier transform (FT) spectrometers at
Imperial College London and the National Institute of Standards and Technology. Analysis of
the FT spectra was carried out in XGREMLIN. Our A constant for the ground level has a lower
uncertainty by a factor of 6 than that of Blackwell-Whitehead et al.
