Fourier-transform sum-frequency surface vibrational spectroscopy with femtosecond pulses.
We present a Fourier-transform spectroscopic technique for investigation of surfaces and interfaces based on IR-visible sum-frequency generation with femtosecond light pulses. The observed spectrum has a resolution that is independent of the input pulse characteristics.
