The production of top quark pairs in association with a hard gluon in e+e- collisions at the NLC provides an opportunity to probe for anomalous t tg couplings, \eg, the chromoelectric and chromomagnetic moments of the top. We demonstrate that an examination of the energy spectrum of the additional gluon jet can yield strong constraints on the size of these two anomalous couplings. The results are shown to be quite sensitive to the cut on the minimum gluon jet energy needed to remove events where the final state b-quark radiates strongly. The possibility of using additional observables to improve the sensitivity to anomalous couplings is briefly discussed. [To appear in \it Physics and Technology of the Next Linear Collider, eds. D.
