Fig. 4From: Properties of Longitudinal Electromagnetic Oscillations in Metals and Their Excitation at Planar and Spherical SurfacesAbsorption spectra calculated with the local (dashed lines) and nonlocal (solid lines) Mie theory and experimental data (dots) extracted from Fig. 9 of [19] for gold spheres with D=2.5, 2.1, and 1.7 nm in toluene (curves 1 and circles, curves 2 and squares, and curves 3 and triangles, respectively). All theoretical spectra are normalized to unity at 4.12 eV and displaced verticallyBack to article page
