STRUCTURAL STUDIES OF KDP AND THE KDP-TYPE TRANSITION BY NEUTRON AND X-RAY DIFFRACTION: 1970-1985

摘要: Abstract Structural work on KH2PO4, KD2PO4, RbH2PO4 and partially-deuterated CsH2AsO4 over the period 1970 to 1985, is fully reviewed. The content predominantly Edinburgh-based programme of neutron-diffraction studies, but other X-ray these isomorphs also included. Following a general presentation 1980, most recent results, conclusions current are discussed in terms four main topics: hydrogen bond, onset structural order below Tc , pressure effects, soft mode. Finally, some suggestions made for further studies closely-related theoretical experimental work.
