Comment: |
one-site-model did not converge, but the authors did not assign the attributes \"strong\" and \"weak\", this was done by RES³T to be consistent with the general philosophy; values were also succesfully compared with re-fitted data from [FAC91] and [CL86], PZC was below pH2 and thus below the experimental range |
