Résumé

The C60/Ag(111) interface is studied by infrared reflection absorption (IRAS) and infrared-visible sum-frequency generation (SFG) spectroscopies for infrared frequencies between 1300 cm-1 and 1500 cm-1. Both IRAS and SFG spectroscopies reveal a vibrational mode located around 1445 cm-1. This mode is assigned to the Ag(2) "pentagonal pinch" mode of C60, which, although being Raman active and infrared inactive in the free molecule, becomes infrared active upon adsorption of the molecule.
