    • The first molecular layers of a new hydrate phase lack the complete lattice of a crystalline phase and are, therefore, noncrystalline (or amorphous) in form, regardless of the formation temperature.

    • The ammonia attached to the dangling hydrogen of the ice surface is not unlike that of one type of ammonia (ammonia II) that dangles in the open channels of the hemihydrate structure. The band position for the O-D bound to ammonia II is near 2300 cm~' (see ref 18).

    • note
    • The composition of an amorphous phase may be regarded as arbitrary, dependent on the activity of the component substances during the formation. This may be generally true, although certain compositions do seem to be favored in H-bonded systems (see ref 1). Here, reference to the amorphous hemihydrate of ammonia is not limited to a precisely 2:1 composition.
