Resonance-assisted hydrogen bond
The resonance assisted hydrogen bond (commonly abbreviated as RAHB) is a strong type of hydrogen bond.
Causes
It is caused by the π-delocalization that involves the hydrogen and cannot be properly described by the electrostatic model alone. This description of the hydrogen bond has been proposed to describe unusually short distances generally observed between O=C-OH∙∙∙ or ∙∙∙O=C-C=C-OH.[1]

gollark: I'm aware it's a deliberate design decision, I just dislike it.
gollark: I don't really like Gemini myself. It's intentionally crippled as a prøtocol.
gollark: Yes. Syscalls will be replaced with HTTP.
