Surface-enhanced Raman spectroscopy is performed on pairs of gold nanoparticles, for which the nanoparticles in each pair have different shapes. The dimers therefore exhibit two plasmon resonances. These structures, termed mixed dimer double-resonance substrates, enable strong field enhancement at pump and Stokes frequencies in surface-enhanced Raman spectroscopy. The extinction spectra of mixed dimers are measured and simulated to identify their plasmon resonances. The experimentally determined enhancement factors of double-resonance structures are compared to those of single-resonance substrates.
