Insights into the microscopic structure of aqueous interfaces are essential for understanding
the chemical and physical processes on the water surface, including chemical synthesis,
atmospheric chemistry, and events in biomolecular systems. These aqueous interfaces have
been probed by heterodyne-detected sum-frequency generation (HD-SFG) spectroscopy. To
obtain the molecular response from the measured HD-SFG spectra, one needs to correct the
measured ssp spectra for local electromagnetic field effects at the interface due to a spatially …
