# Effect of temperature on Hydrogen Bonding?

We had this question in a test and I am not sure of the answer

Q. Temperature changes don't effect the extent of inter and intra molecular hydrogen bonding. State true or false.

I think that raising temperature would increase the kinetic energy of molecules and would thus lead to weakening of inter molecular hydrogen bonds. But am not sure what will happen to intra molecular hydrogen bonds...

For e.g. if ortho-nitrophenol is heated, will the intra molecular hydrogen bonds between hydrogen of the hydroxyl group and oxygen of the nitro group break?

Any ideas/suggestions?

Take for example nitrous acid, which exhibits two unique $\ce{O-N-O}$ bond angles. One of these bond angles (the smaller one) results from intramolecular hydrogen bonding between the hydrogen and the oxygen on the other end. This occurs because there free-rotation is permitted around the single bonds in the nitrous acid molecule. The energy difference between the two structures is calculated to be $0.45~\mathrm{kcal~mol^{-1}}$ or $1880~\mathrm{J~mol^{-1}}$.
