“…The details of the 2D-IR spectrometer have been explained elsewhere. , In brief, the 2D-IR spectrometer, in a pump–probe geometry, has been designed and constructed around a Ti-sapphire amplified laser system. The current setup has been upgraded with the use of an MCT array detector (2X 32, CDP Inc., Russia) instead of the previously used single-element MCT detector.…”

“…Infrared spectroscopy is highly sensitive to the electrostatic environment surrounding a vibrational probe. In particular, carbonyl stretching line shapes are sensitive to H-bond populations; an H-bond red-shifts the carbonyl frequency compared to the free carbonyl (Figure ). Characterizing interfacial effects on confined environments necessitates a molecular understanding of the relationship between composition, interfacial charge, localization, and their effects on interfacial environments. , Solvation dynamics at the interface are essential for a complete description of interfacial environments. , Ultrafast infrared spectroscopy offers the ability to probe the interfacial dynamics at the RM interface, resolving the changes introduced between the aqueous core of the RM and charged encapsulants. , This study leverages two-dimensional infrared spectroscopy (2D IR) to probe the Span-60 ester carbonyl and measure the effects of heterogeneous surfactant composition and charge–charge interactions between the interface and PEI on water dynamics on the subpicosecond time scale. The ester carbonyls (Figure A) are precisely located in the region between the hydrophilic headgroup region and the hydrophobic tails and are therefore ideal probes for the interfacial environment.…”
