Abstract
By fitting model values for physical quantities for PbDPO4 crystal in theoretical expressions for soft mode frequency, dielectric constant and loss tangent derived in our earlier paper for PbHPO4 crystal temperature variations of these quantities have been calculated near transition temperature. Present results agree with experimental data reported in the literature. Isotope effects on both transition temperature and Curie-Weiss constant have been explained for PbDPO4 crystal beautifully
