    • It should be noted, however, that the dielectric function of the surrounding environment differs for that of the suspended particle (water) compared to that of the immobilized particle (air). If the ambient dielectric function were the same for both cases, immobilization would result in an even greater red shift than presented here.

    • It was determined that using more than 40 terms does not significantly alter the value for polarizability.

    • The extinction maxima on silver calculated with a gap of 1.2 nm are 617 and 663 nm, respectively, for 60- and 80-nm gold particles. This calculation exemplifies the extreme sensitivity of this system to nanoparticle-substrate separation.

    • The laser focal volume was estimated as a cylinder with a diameter equal to that of the focused beam waist and a height equal to the focal depth.

    • -1 maximize with the immobilized 80- and 60-nm particles, respectively. However, smaller signals for these bands resulted in smaller differences in EFs, precluding the ability to draw definitive conclusions.
