Two different complexes of ammonia with two different conformers of glycidol have been characterized by Fourier transform microwave spectroscopy. In both complexes NH3 is linked to the alcohol molecule through an O-H•••N (stronger) and an N-H•••O (weaker) hydrogen bond. The determined V3 barriers to internal rotation of the ammonia moiety, 3.522(2) and 2.270(1) kJ/mol for the G1-NH3, and G2-NH3, respectively, correspond to the energy of the N-H•••O interaction. Structural and energetic features of the hydrogen bonds are given.

Abstract

Two different complexes of ammonia with two different conformers of glycidol have been characterized by Fourier transform microwave spectroscopy. In both complexes NH3 is linked to the alcohol molecule through an O-H•••N (stronger) and an N-H•••O (weaker) hydrogen bond. The determined V3 barriers to internal rotation of the ammonia moiety, 3.522(2) and 2.270(1) kJ/mol for the G1-NH3, and G2-NH3, respectively, correspond to the energy of the N-H•••O interaction. Structural and energetic features of the hydrogen bonds are given.
