Title: Electron Beam
Post by: completenovice on July 22, 2008, 05:05:09 PM

Hi,

Does anyone know what the effect on the water molecule could be if you passed an electron stream through it?

If there was no effect why not?

Ta

ps: it may be a rubbish question but I am a complete novice.

thanks again

Water is a polar molecule, therefore it could arrange itself such that the delta+ end forming attraction with the stream of electrons. Perhaps some will get deflected due to the lone pair on oxygen atoms as well as the delta- end.

Well, because we deal with huge quantity of energy there is possibility for formation of ionic water molecules in excited state (singlet or/and triplet) which have very different chemical properties. This may be a reason for intense declusterization or intense clusterization (as you know the water exist in clusters of approximately 70-1000 molecules), or reason for generating oxygen or hydrogen radicals.... there are 1000....00000 possibilities
