Mid-Infrared Comb-Based Fourier Transform Spectroscopy of Halogenated Volatile Organic Compounds

Broadband high-resolution spectra of two key atmospheric species, methyl iodide (CH3I) and dibromomethane (CH 2 Br 2 ), are measured around 3 μm using a comb-based Fourier transform spectrometer and assigned with the help of the semi-automatic fitting in PGOPHER.
