▲图1 CIF中记录温度的项目 上图中温度为193.00(10)是带标准偏差的,表示193.00±0.10 K,是一个温度范围,如果没有标准偏差,如193.00,就表示是193.00 K,是一个确定值,晶体在测试的时候,其温度是一个范围显然比其是一个确定值要合理的多。 通常来讲,精修生成的CIF中上述两个项目记录的温度均是带有标准偏差的,如果不是的话,可能需要手动添加,一般来说温度偏差在±1~2 K,在Olex2中,可在Report>>Diffraction中填写,当然也需要在ins文件中填入相应的TEMP指令,否则可能会触发B级警报PLAT196(参阅视频“CheckCIF警告PLAT196的解决:https://www.bilibili.com/video/BV1cW4y1i7yB”),如图2所示。
