What a funny & pleasant piece of discussion !
Given any physical quantity "Something", having any kind of dimension
(even as awful as inches^2*gallons*pounds^-3)
Would it exist any room for a discussion about the dimension of
2*Something ? And what about 1*Something ?

the comments exist, but implicitly in the cited litterature...
Now, I am still wondering whether external "stresses" on biological crystals
could indeed induce such unexpected birefringen
develop such "stress birefringence"...

Although this is not a very important issue..., I am a bit surprised by
Gerard's insistance for a 'stop calling rmsd "rms deviation"'. Isn'it a
general term in statistical studies, valid for distances separating
homologous atoms as well as for any other factor (B fa
Yes indeed ! H2 is one product of H2O radiolysis by recombination of two H
radicals.
Whether or not the cleavage of iodine (quite efficient under X-rays) is a
factor increasing H2 production, I don't know.
