I would say you cannot measure the diffraction pattern of a single
biological molecule accurately thus far, because biological molecules are
not strong scatters and can be damaged easily. For other molecules,
actually you can!
In high-resolution electron microscopy, the diffraction pattern in the
The question is, as I rephrased it, assuming we are able to measure the
diffraction pattern of a single molecule with acceptable accuracy and
precision (comparable to what we have now for the common crystals), is it
better than we measure the diffraction spots from a crystal, given that the
Dear Steven,
Thank you for your reply! I understand that it is nearly impossible to
measure the diffraction of a single molecule, and I am just bringing this
up as a thought experiment to help understand the basics in
crystallography. But I never thought that some molecules actually allow
such
Hi Jacob,
Thanks a lot for your reply! Yes, by comparable data quality I did mean the
comparable resolution and SNR. I now understand the original question and
kinda confirm what I thought. But I am also learning myself and I don't
quite get why the continuous sampling would get rid of the phase
