摘要：

The C-60/Ag(111) interface is studied by infrared reflection absorption (IRAS) and infrared-visible sum-frequency generation (SFG) spectroscopies for infrared frequencies between 1300 and 1500 cm(-1). Both IRAS and SFG spectroscopies reveal a vibrational mode located around 1445 cm(-1). This mode is assigned to the A(g)(2) ''pentagonal pinch'' mode of C-60, which, although being Raman-active and infrared-inactive in the free molecule, becomes infrared-active upon adsorption of the molecule.
