dielectric constants

Dear RASMBers

We are running some preliminary experiments in a DELSA (Doppler
electrophoretic light scattering analyser) instrument and would like to
know the dielectric constants (e) of some buffers that we're planning to
use. Specifically:

phosphoric acid
MES (2-(N-morpholino) ethanesulphonic acid)

We have looked in the Handbook of Chemistry and Physics and so far have
only found one value of e that is of any use to us- for acetic acid e =

If anyone could fill in some of the gaps, we'd be very grateful.
Thanks and best wishes to all-

Olwyn Byron and Steven McDade
