π‐Type H‐bonds that are not found in bulk liquid phases, where σ‐type H‐bonds prevail, were detected for the dye rhodamine 800 at air/water and fused silica/water interfaces (see picture) by interface‐selective fourth‐order nonlinear ( χ (4) ) Raman spectroscopy in the frequency domain. This new method allows vibrational spectra of organic solutes at liquid interfaces to be obtained in the whole fingerprint region (200–2800 cm −1 ).
