Quantifying Conformational Isomerism in Chain Molecules by Linear Raman Spectroscopy: The Case of Methyl Esters

Abstract: The conformational preferences of the ester group have the potential to facilitate the large amplitude folding of long alkyl chains in the gas phase. They are monitored by Raman spectroscopy in supersonic jet expansions for the model system methyl butanoate, after establishing a quantitative relationship with quantum–chemical predictions for methyl methanoate. This requires a careful analysis of experimental details, and a simulation of the rovibrational contours for near-symmetric top molecules. The technique… Show more

“…NoisySignalIntegration.jl was developed as a solution to this problem. While the package was developed specifically for the determination of band area uncertainties in the context of molecular spectroscopy (Gawrilow & Suhm, 2021;Karir et al, 2019;Zimmermann et al, 2021), it is applicable in any research area where signals (peaks, lines, bands, etc.) 1 in x-y data need to be integrated and a thorough uncertainty analysis is desired.…”

“…An dieser Stelle sei darauf hingewiesen, dass in Ref. [45] die RI-Näherung nur für J-Integrale (MARI-J ) eingesetzt wurde, weil in Turbomole < 7.5 RI-JK -Rechnungen schlechter parallelisiert als RI-J -Rechnungen und damit effektiv langsamer waren. Daher können die im Folgenden dargestellten Zahlen geringfügig von denen in Ref.…”
