I think that "atomic resolution" is one of those terms which mean different things to different people. There are clearly two groups among crystallographers, those who call it atomic resolution when you can resolve non-hydrogen atoms and those (including myself) who stand up for a little guy :) Apparently, it should mean something else in NMR. I would argue that by "xray standards" every NMR structure is of atomic resolution in limited sense (i.e. only a subset of atoms is resolved). Individual peaks associated with individual atoms in NMR are *resolved*, right? If peaks fuse, there is no NMR structure at all.
