Optical Probes of Organic Thin Films

General Properties: Dipole origins of the three main classes. Experimental characteristics for comparison. Polarization, Freznel coefficients and the Kramers-Kronig relation. The Linear Dipole Techniques - Primarily Electronic Origin: Spectrophotometry. Ellipsometry. Microscopy and interferometry. X-ray scattering and diffraction. Surface electromagnetic wave techniques - electronic and vibrational. Integrated optics approaches. The Linear Dipole Techniques - Vibrational Origins: Transmission IR spectroscopy. External reflection-absorption IR spectroscopy. Multiple internal reflection spectroscopy. Other configurations. Surface Brillouin scattering. The First Order Induced Dipole Techniques: Unenhanced surface Raman. Enhanced Raman spectroscopy. The Second Order and Higher Non-Linear Polarization Techniques: NLO background. Surface second harmonic generation. Higher order non-linear optical probes. Conclusions. Conclusions and Final Comments. 630 lit. refs. approx., 110 illus.
