Adducts of NH(3) with the Conformers of Glycidol: A Rotational Spectroscopy Study

Two locks accept the same master key: Two different complexes of ammonia with two different conformers of glycidol have been characterized by Fourier transform microwave spectroscopy (see picture; gray C, blue N, red O, white H). In both complexes NH3 is linked to the alcohol molecule through an O[BOND]H???N (stronger) and an N[BOND]H???O (weaker) hydrogen bond. Structural and energetic features of the hydrogen bonds are given.
