Research Overview

Dr. Pei-Ling Luo's laboratory team is developing mid- infrared, time-resolved dual-comb spectroscopy to investigate the infrared spectra of key atmospheric free radicals and their associated reaction kinetics. Recently, Dr. Luo’s group successfully established a new spectrometer based on synchronized two- color, time-resolved dual-comb spectroscopy, which enables simultaneous measurements in two distinct molecular fingerprint regions (3–5 μm and 7–10 μm) with microsecond-level time resolution. Using this new approach, the team can synchronously monitor multiple reactive species, including precursor molecules, reaction intermediates, and reaction products. Dr. Luo’s laboratory primarily applies this unique spectroscopic technique to perform high-resolution spectral measurements and quantitative concentration determination of important radical species such as OH, HO2, and CH2OO. Building on these capabilities, the group further investigates key atmospheric reaction mechanisms and kinetics involving these radicals. In addition to providing accurate reaction rate constants, this research can also yield critical experimental data such as product branching ratios and mechanistic pathways, supporting more robust assessments of the impacts and significance of these reactions within atmospheric chemistry.
