In order to carry out such an investigation, we have developed a new experimental setup that combines UV pulsed laser photolysis and a room-temperature flow cell with a Fourier-transform millimeter-wave emission spectrometer. A multiple-pulse acquisition protocol enables time-resolved detection of transient species over millisecond time scales to improve signal-to-noise ratios through averaging. This system enables in situ observation of transient species and their vibrationally excited states under thermal conditions, demonstrating the capabilities of a new instrument that can record time-resolved rotational spectra. A total of 120 transitions were measured and used to determine accurate spectroscopic parameters for CH2OO (\u03bd7 = 1).<\/jats:p>","DOI":"10.1021\/acs.jpca.6c02165","type":"journal-article","created":{"date-parts":[[2026,8,12]],"date-time":"2026-08-12T15:02:17Z","timestamp":1786546937000},"page":"6678-6684","source":"Crossref","is-referenced-by-count":0,"title":["Time-Resolved Fourier-Transform\nMillimeter-Wave Spectroscopy\nof the Simplest Criegee Intermediate, CH2OO, in Its \u03bd7 = 1 State"],"prefix":"10.1021","volume":"130","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2215-1750","authenticated-orcid":true,"given":"Ning L.","family":"Chen","sequence":"first","affiliation":[{"name":"Univ.
