Serine molecules in the gas-phase as well as in solution in water have been investigated using density functional theory. Solvent and conformer effects as well as zero-point vibrational corrections have been taken into account. For the non-vibrating molecule, the best agreement is obtained when solvent and conformer effects are included. Zero-point vibrational corrections improve the agreement with experimental values, leading to a root mean square deviation of 0.05 ppm for chemical shifts and 0.7 Hz for spin-spin coupling constants.}10aFrance10aImagerie cérébrale10areseau_national1 aAtieh, Z1 aAllouche, A R1 aGraveron-Demilly, D1 aAubert-Frecon, M uhttps://www.creatis.insa-lyon.fr/site7/en/publications/ATIE-11
