I wish to write that some variables in a scientific document can be respectively identified (as/by) some values... For instance,

"...where a,b and c correspond to the energies the spinor and the bosonic fields may carry and in the free theory, they can be respectively identified as 1,2 and 3."

Is "as" correct or should I write "by" or something else? Any help would be appreciated.

Thanks!
