get_poly_const(mol_type, exchange = "HD")
character, "poly" or "oligo". If "oligo" then the calculated constants are multiplied by c according to the considered condition (base, water or acid).
type of exchange - "HD" for hydrogen to deuterium, "DH" for deuterium to hydrogen (back-exchange). Default "HD".
list of Ka,Kb and Kw corresponding to the chosen mol_type
