Title

Angle-dependent Temporal Profiling of Sum Frequency Generated Response

Abstract

Interactions at surfaces and interfaces are where many phenomena that interest chemist occur, such as adhesion, bacterial survival, electrochemistry, and heterogeneous catalysis. Vibrational sum frequency generation (VSFG) spectroscopy is a powerful analytical technique because it provides nature about molecular and atomic orientations at the surface. However due to nonresonant response from the sample it can be difficult to analyze data and incorrect conclusions can easily be drawn. Analysis of Si 111 samples has shown that there is angle dependence to the SFG response that would impact the use of current techniques to minimize the nonresonant signal.
