Probing matter with light in the mid-infrared provides unique insight into molecular composition, structure, and function high sensitivity. However, laser spectroscopy this spectral region lacks broadband or tunable sources efficient detectors available visible near-infrared. We overcome these challenges an approach that unites a compact source of phase-stable, single-cycle, pulses room temperature electric field-resolved detection at video rates. The ultrashort correspond to frequency combs span 3 27 μm (370 3333 cm-1), are measured dynamic range >106 resolution as 0.003 cm-1. highlight brightness coherence our apparatus gas-, liquid-, solid-phase extends over bandwidths comparable thermal infrared synchrotron sources. This combination enables powerful avenues for rapid biological, chemical, physical properties specificity.

Reactive oxygen species (ROS) play a central role in adverse health effects of air pollutants. Respiratory deposition fine particulate matter can lead to the formation ROS epithelial lining fluid, potentially causing oxidative stress and inflammation. Secondary organic aerosols (SOA) account for large fraction matter, but their is unclear. Here, we quantify compare yields potential isoprene, β-pinene, naphthalene SOA water surrogate lung fluid (SLF). In pure water, isoprene β-pinene were found produce mainly OH radicals, whereas produced H2O2 O2•-. The total molar 11.8% 8.2% decreased 8.5% 5.2% SLF, which be attributed removal by antioxidants. A positive correlation between peroxide concentration yield suggests that (hydro)peroxides may an important from biogenic SOA. was 1.7% increased 11.3% SLF. This strong increase likely due redox reaction cycles involving environmentally persistent free radicals (EPFR) or semiquinones, antioxidants, oxygen, promote anthropogenic aromatic precursors.
