Infrared microscopy and surface-enhanced Raman scattering of Ag colloid-2,2'-bipyridine film

Abstrakt

IR spectra of 2,2'-bipyridine from Ag colloid-bpy film by IR microscopy. Their comparison toepends on both the spacer and the porphyrin concentrations. dipole moment with density is found in the case of molecules with larger value of polarizability.

Howeer, with increasing non-sphericity of molecules the the density effect decreases.
