The matrix isolation method is used to obtain the spectra of molecules in solid neon in the 1000--400-nm range. All the recorded bands are referred to transitions within the 5f /sup 2/ configuration of U/sup 4 +/ ion in the field of four fluorine ions. The interpretation assumes the case of a weak crystal field in which the terms of U/sup 4 +/ ion with different J are not mixed up. It is concluded that the UF/sub 3/ molecule has the structure of either a tetrahedron or a slightly distorted tetrahedron.
