Abstract
The process of sublimation of L-serine hydroxyl amino acid was investigated by mass-spectrometry. The range of temperatures corresponding to vaporization without decomposition was determined. The value of sublimation enthalpy was obtained for the first time. The calculation of intermolecular H-bond energy was carried out. The conformational search was realized. Geometric parameters were defined more by quantum chemical calculations.

Keywords: sublimation, enthalpy of sublimation, L-serine, energy of intermolecular H-bond, conformer, geometric parameters, quantum chemical calculations
