一个晶体结构精修的问题,精修后最大残余峰Q1的电子密度为1.21,最近的H19原子距离该Q1为2.667埃,Q1周围只有一个残余峰Q4,电子密度为0.64. 审稿人提出的问题如下:The maximum residual density peak in the final difference Fourier map is 2.67Å from H19. Please state the height and give an explaination as to why it is still there and has not been modelled as disorder of some sort?
请高人指点我该如何答复。
