Zeeman studies of a single crystal of GeCl₄ have been carried out on a previously described pulsed FT NQR spectrometer. The technique for growing single crystals from liquid samples is described. The Zeeman-split spectrum for each of the resonances at v₁ = 25.4493, v₂ = 25.7133, v₃ = 25.7354, and v₄ = 25.7457 MHz reveals four quadruplets. The asymmetry parameters found lie in two groups of average values n = 0.035 and n = 0.078, much lower than the previously reported value of n = 0.35 obtained from a polycrystalline sample. The crystal of GeCl₄ is found to be orthorhombic with mmm or D_2n symmetry. From the directions of the field gradient axes the interbond angles have been calculated and show that the GeCl₄ molecule is a slightly distorted tetrahedron.
