[交流] 呋喃环上氧原子和碳原子无序求助

一晶体中,呋喃环上氧原子和碳原子存在无序。
一般叔丁基无序描述为
The methyl group was found to be disordered over two orientations.
The occupancies of the disordered positions C1/C1', C2/C2' and C3/C3'
were refined to 0.875(14)/0.125(14). Suitable restraints were
applied to the C---C distances involving the disordered atoms.

该晶体中,呋喃环上O1和C15原子无序,占有率为0.53:0.47,那
exptl refinement 该怎样描叙呢?

可以参照陈晓明版的单晶解析课本里的例子

The O1 and C15 on furan ring was found to be disordered over two orientations.
The occupancies of the disordered positions O1/O', C15/C15'
were refined to 0.53/0.47, Suitable restraints were
applied to the C---O and C---C  distances involving the disordered atoms.
能不能这样写啊,嘿嘿

你还是想想怎么确定你的占有率的?
小心人家提问啊
