We have studied tunneling into individual Au nanoparticles of estimated diameters 2--5 nm, at dilution refrigerator temperatures. The I-V curves indicate resonant tunneling via discrete energy levels of the particle. Unlike previously studied normal metal particles of Au and Al, in these samples we find that the lowest energy tunneling resonances are split into clusters of 2--10 subresonances. Such effects appear to be increasingly important in smaller grains, as might be expected from the larger characteristic energies.
