Title:The Shape Of Levodopa: A Laser Abalation Rotational Study
Author(s):Novo, Miguel Sanz

Subject(s):Structure determination
Abstract:The rotational spectrum of neutral levodopa (L-dopa), an aminoacid precursor of neurotransmitters dopamine \footnote{C. Cabezas, I. Pena, J. C. Lopez and J. L. Alonso, J. Phys. Chem. Lett., 2013, 4, 486–490.}, norepinephrine (noradrenaline) and epineophrine (adrenaline), has been investigated for the first time using a broadband chirped pulse FTMW spectrometer coupled with a laser ablation source (LA-CP-FTMW). The spectroscopic parameters derived from the analysis of the spectrum conclusively identify the existence of three conformers of levodopa. The $^{14}$N nuclear quadrupole coupling constants have been analyzed, probing the existence of stabilizing N-H-$\pi$ interactions for the observed structures. \begin{itemize} \item \textbf{Acknowledgments:} The authors thank the financial fundings from Ministerio de Ciencia e Innovacion (CTQ2016-76393-P and PID2019-111396GB-I00), Junta de Castilla y Leon (VA077U16 and VA244P20) and European Research Council under the European Union's Seventh Framework Programme (FP/2007-2013) / ERC-2013-SyG, Grant Agreement n. 610256 NANOCOSMOS, are gratefully acknowledged.
