Synonyms Used in print (James A. Ibers et al., "Proton magnetic resonance...)The **f layers are stacked normal to the [ 111 ] axis with the lower oxygens of one layer directly above the upper oxygens of the neighboring lower layer , in such a manner that the repeat is every three layers . The **f layers are stacked normal to the [ 111 ] axis with the lower oxygens of one layer directly above the upper oxygens of the neighboring lower layer , in such a manner that the repeat is every three layers . The bond angles and distances are all within the expected limits and the volume per oxygen is about normal . However , the possible absence of a center of symmetry not_only moves the hydrogen_atom off **f , but also allows the oxygen atoms to become nonequivalent , with **f at **f and **f at **f ( space group **f ) , where **f represents the oxygens on one side of the **f layers and **f those on the other side . However , the possible absence of a center of symmetry not_only moves the hydrogen_atom off **f , but also allows the oxygen atoms to become nonequivalent , with **f at **f and **f at **f ( space group **f ) , where **f represents the oxygens on one side of the **f layers and **f those on the other side .
