2-CEME AND NOT 2-CEME: MULTI-PULSE TECHNIQUES AS APPLIED TO THE ROTATIONAL SPECTRA OF 2-CHLOROETHYL METHYL ETHER AND 1,2-EPOXYBUTANE

Abstract

Strong-field coherence breaking (SFCB)\footnote{A.O Hernandez-Castillo, Chamara Abeysekera, Brian M. Hays, Timothy S. Zwier, “Broadband Multi-Resonant Strong Field Coherence Breaking as a Tool for Single Isomer Microwave Spectroscopy.” \textit{J. Chem. Phys.} \textbf{145}, 114203 (2016).} and other multi-pulse techniques provide promise for greatly accelerating the rate at which complex spectra can be assigned. Last year, I presented on the use of SFCB for simplifying the spectra of allyl chloride.\footnote{Riffe, Erika; Zwier, Timothy S.; Hernandez-Castillo, Alicia O.; Fritz, Sean; Shipman, Steven; Johnson, Erika. “The Conformer Specific Room-Temperature Rotational Spectrum of Allyl Chloride Utilizing Strong Field Coherence Breaking, International Symposium on Molecular Spectroscopy,” 73rd International Symposium on Molecular Spectroscopy, Talk TI11 (2018).} Now, I present an update to the use of SFCB and other multi-pulse techniques for analysing rotational spectra collected at and near room temperature, using the molecules 2-chloroethyl methyl ether (2-CEME) and 1,2-epoxybutane as test cases. The use of these techniques and their significance in the simplification of complex spectra will be discussed.
