Abstract

The three lowest energy levels of

{Ho}^{3 +}

in

{LiYF}_{4}

are determined by submillimeter EPR spectroscopy. The ground state is a

Γ_{3, 4}

doublet. The next excited levels are two

Γ_{2}

singlets at 6.8 and 23.8

{cm}^{- 1}

. The

g_{∥}

value for the

Γ_{3, 4}

doublet is 13.3 ± 0.1. The couplings between the two

Γ_{2}

singlets, and between the

Γ_{3, 4}

doublet and the first

Γ_{2}

singlet are determined.
