Vibrational sum frequency generation (SFG) spectroscopy is a nonlinear optical technique that combines the fields of infrared and visible light to provide information about the molecular structure and dynamics of surfaces and interfaces. It involves the interaction of two incident laser beams with different frequencies (typically an infrared beam and a visible beam) at a sample surface, resulting in the generation of a new beam with a frequency equal to the sum of the two incident frequencies. By varying the frequency of the infrared beam, the vibrational modes of the molecules at the surface can be selectively excited, providing a detailed spectral fingerprint of the surface composition and structure.
