The symmetry classification of the states of a pair of interacting ions in a crystal is obtained by a formal symmetry reduction not dependent upon any assumptions about the details of the interaction. The theory is given in versions valid with or without spin-orbit coupling, and for pairs in magnetic or non-magnetic hosts. Some discrepancies with previous work are discussed.
