What Does VSFG Stand For?

VSFG stands for Vibrational Sum Frequency Generation

Vibrational Sum Frequency Generation (VSFG) is a nonlinear optical technique used to study molecular interactions at interfaces and surfaces. By combining two laser beams at different frequencies, VSFG generates a third beam with frequencies that correspond to the vibrational modes of molecules. This method provides detailed information about molecular orientation, conformational changes, and surface chemistry, making it a valuable tool in fields such as chemistry, materials science, and biology.
