Resonant energy transfer between cold Rydberg atoms was used to determine Rydberg atom energy levels, at precisions approaching those obtainable in microwave spectroscopy. Laser cooled {sup 85}Rb atoms from a magneto-optical trap were optically excited to 32d{sub 5/2} Rydberg states. The two-atom process 32d{sub 5/2}+32d{sub 5/2}{yields}34p{sub 3/2}+30g is resonant at an electric field of approximately 0.3 V/cm. This process is driven by the electric dipole-dipole interaction, which is allowed due to the partial f character that the g state acquires in an electric field. The experimentally observed resonant field, together with the Stark map calculation is used to make a determination of the {sup 85}Rb ng-series quantum defect {delta}{sub g}(n=30)=0.00405(6)
