Heterodyne-detected electronic sum frequency generation (HD-ESFG) spectroscopy is newly developed to obtain complex electronic chi(2) spectra of interfaces for a simultaneous detection bandwidth broader than 100 nm. HD-ESFG provides linear chi(2) spectra that have unambiguous information on the "up" versus
