Infrared, Raman and surface-enhanced resonance Raman scattering of N-butylimido, ethyleneamine perylene (PTCD-NH(2)): Single-molecule detection using colloidal silver and silver island films.

摘要

The vibrational spectra and the surface-enhanced (resonance) Raman scattering (SERS/SERRS) of a perylene dye containing a terminal NH2 group, n-butylimido, ethyleneamine perylene (PTCD-NH2) have been studied. The infrared, Raman and resonance Raman spectra of the material were recorded and vibrational fundamentals assigned. The vibrational assignments of fundamentals were aided with an ab-initio Hartree-Folk at 6-31G level of theory. Langmuir-Blodgett monolayers of the neat material were fabricated and the pi-A isotherms recorded. Mixed monolayers were also studied for applications in SERBS. The spectra of evaporated thin solid films were obtained and a complete spectroscopic characterization of these films is presented in the thesis. Single molecule detection of PTCD-NH2, adsorbed on colloidal silver and silver island films are investigated using surface enhanced resonance Raman spectroscopy and Langmuir-Blodgett films.
