Solid equimolar complexes of pyridine, 2-picoline, and 2,6-lutidine N-oxides with iodine are studied. External pressure can induce a first-order phase transition in the latter complex. The solid-phase dipole moments of neighboring molecules of comple

The static and complex dielectric permittivities and dc electrical conductivities of solid oxalic, malonic, and succinic acids were measured. The relaxation times of single crystal blocks (3–5 days) and mean relaxation frequencies of molecules and

Solid succinic acid tends to undergo fast polymorphous transitions. This phenomenon, and also realization of numerous bifurcation points make its autoionization processes very diverse. The polymorphism of the acid is reflected in its optical spectra.
