Sum Frequency Generation Spectroscopy (SFG) is a technique used to analyze surfaces and interfaces. This spectroscopy method utilizes sum frequency generation, where two light beams mix at a surface and generate an output beam with a frequency equal to the sum of the two input frequencies. From the experiment setup and the output beam, one can deduce the composition, orientation distributions, and some structural information of molecules on a surface. SFG has advantages in its ability to be monolayer surface sensitive, ability to be performed in situ (for example aqueous surfaces and in gases), and not causing much damage to the sample surface. 3, record 1, English, - sum%2Dfrequency%20generation

Cette technique est obtenue par mixage non linéaire (synchronisation) d’une onde laser visible fixe (laser YAG [en grenat d'yttrium et d'aluminium] doublé) et d’une onde laser infrarouge accordable (laser à électrons libres). Le signal de fréquence somme devient résonnant quand la fréquence infrarouge est voisine de celle d’un mode de l’adsorbat. 3, record 1, French, - g%C3%A9n%C3%A9ration%20de%20la%20fr%C3%A9quence%20somme
