Cover Picture: Monitoring Aqueous Phase Reactions by Operando ATR‐IR Spectroscopy at High Temperature and Pressure: A Biomass Conversion Showcase (Chemistry ‐ Methods 11/2021)

The Front Cover shows an attenuated Total Reflection Infrared spectroscopy (ATR-IR) probe monitoring a chemical reaction in the liquid phase, particularly water, at demanding conditions. The light penetrates few microns deep in proximity of the ATR-IR probe and thus any IR-active entity in that range is probed. This research systematically addresses the challenges associated with acquiring operando ATR-IR spectra for liquid/aqueous phase reactions, which is essential for better understanding of chemical reactions in the liquid phase.
