Crystals of ThSiO/sub 4/--U/sup 4 +/ were grown by the flux method. Absorption and emission spectra were recorded from 4000 to 30 000 cm/sup -1/ at liquid helium and various higher temperatures. The transitions were assigned and fit to a semiempirical Hamiltonian with adjustable parameters via a least squares procedure. The crystal field parameters for U/sup 4 +/ in ThSiO/sub 4/ were compared to those for U/sup 4 +/ in other hosts.
