Since MnF2 1 has an absorption spectrum which contains a wealth of structure at low temperatures, 2 has cubic field excited states which are well separated in energy and easily identifiable, 3 has a very simple ground state, and 4 has a well studied magnon structure, an investigation was undertaken of the excited states in the hope of observing other magnetic dipole transitions and their accompanying magnon sidebands. This study was undertaken with a view to examine the success of crystal field theory in a low symmetry crystal, to understand, in a general way, the differences and similarities between the magnon sidebands in several excited states of the Mn2 ion, and to determine the importance of spin assisted transitions in the overall absorption spectrum. The conclusions of such a study have obvious application to a diversity of other materials. Author
