标题: How the hydrogen bond distance is measured ?
Hi everyone
I would like to ask about the hydrogen bond distance measure.? Is the distance considered from the donor to acceptor heavy atoms?
Or just from the hydrogen to acceptor?

Sincerely,

Usually, the H-bond distance is defined as the length between donor and acceptor heavy atoms.

I think no general rules here.
People just use their own ways they think more appropriate, and also for different type/kind of HBs, it can be quite different. For example, if the angle is far from 180 deg, the distance from donor to acceptor can be misleading.
