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 NH 3 is linked to the alcohol molecule through an OH⋅⋅⋅N (stronger) and an NH⋅⋅⋅O (weaker) hydrogen bond. Structural and energetic features of the hydrogen bonds are given.
