Dear Tim, and Arpita and Doeke,
Basically structure is not affected (as evidenced by our Fisher and Helliwell
database survey in Acta Cryst) but kinetics is affected ie everything is slower
in D2O and can thereby be toxic.
Greetings

Hi Doeke,
if I remember correctly, D2O is poisonous and bacteria grow with reduced
growth rate.
The effect of the greater mass may not be totally insignificant.
Best,
Tim

Dear all,
We have a PDRA position at Diamond to work on developing new methods for
time-resolved crystallography. You will work closely with a number of groups at
Diamond and beyond to improve approaches for both SSX and SFX.

Hi Arpita,
H and D have the same number of electrons (1). The D nucleus has an extra
neutron, changing its mass and therefore its vibrational energy levels. That
can affect hydrogen bonding patterns, although I would expect the effect to be
relatively minor (see e.g. Fisher and Helliwell, Acta
