The effects of irradiation by picosecond ultraviolet (266 nm) and visible (532 nm) pulses of CO-covered Ni(111) and NiO(111)/Ni(111) surfaces were investigated by infrared-visible sum-frequency generation (SFG) spectroscopy. As a result of the irradiation of UV pulses, the SFG signal by the v=1←0 ba...
