The Rotational Spectrum of Tyrosine Pérez Cuadrado, Cristobal Mata López, Santiago Cabezas, Carlos López Alonso, Juan Carlos Alonso Hernández, José Luis Producción Científica In this work neutral tyrosine has been generated in the gas phase by laser ablation of solid samples, and its most abundant conformers characterized through their rotational spectra. Their identification has been made by comparison between the experimental and ab initio values of the rotational and quadrupole coupling constants. Both conformers are stabilized by an O–H•••N hydrogen bond established within the amino acid skeleton chain and an additional weak N–H•••π hydrogen bond. The observed conformers differ in the orientation of the phenolic −OH group. 2017-03-20T12:58:46Z 2017-03-20T12:58:46Z 2015 info:eu-repo/semantics/article Journal of Physical Chemistry A, 2015, 119 (16), pp 3731–3735 http://uvadoc.uva.es/handle/10324/22665 10.1021/acs.jpca.5b01792 Journal of Physical Chemistry A eng http://pubs.acs.org info:eu-repo/semantics/openAccess http://creativecommons.org/licenses/by-nc-nd/4.0/ © American Chemical Society Attribution-NonCommercial-NoDerivatives 4.0 International American Chemical Society SI
