Experiment E97‐110 was performed at the Thomas Jefferson National Accelerator Facility in Hall A to provide a precise measurement of the moments of the neutron and 3He spin structure functions. A longitudinally‐polarized electron beam was scattered from a longitudinally or transversely polarized 3He target. The extended Gerasimov‐Drell‐Hearn integral and other moments of the neutron and 3He spin structure functions were extracted at very low momentum transfers (0.02<Q2<0.3 [GeV/c]2). These data allow us to make a benchmark check of Chiral Perturbation Theory calculations in a region where they are expected to be valid. In these proceedings, the experimental details are discussed and preliminary results on the moments of the spin structure functions are presented.
