I searched for this on Google but I only got research articles in the SERP. I know of the concept of hydrogen bonds, that they are a special class of Van Der Waalvan der Waals forces between highly electronegative atoms ($\ce{F/O/N/Cl})$ and the hydrogen atom. I am asking if Deuteriumdeuterium also exhibits the same hydrogen bonding, and how does its "D"$\ce{D}$ bond" compare to the hydrogen's original "H"$\ce{H}$ bond"?
