Investigation of hydrogen bond dynamics in NH₄IO₃·2HIO₃ crystal by NQR

Baisa, D.F.; Barabash, A.I.; Vertegel, I.G.; Chesnokov, E.D.; Ovcharenko, A.I. (Functional Materials, 2006)

The pressure dependence of the quadrupole coupling constant e²Qqzz and electric field gradient tensor asymmetry parameter η have been obtained from the analysis of ¹²⁷l nuclear quadrupole resonance spectra at 77 K. It was ...
Investigation of I¹²⁷ NQR spectra of the mixed (BiI₃)₍₁₋n₎ •(PbI₂)n semiconducting layered crystals

Gnatenko, Yu.P.; Barabash, A.I.; Vertegel, I.G.; Chesnokov, E.D.; Ovcharenko, A.I.; Pogrebnyak, S.V. (Functional Materials, 2010)
NMR and NQR investigation of the lattice dynamics in (CH₃)₂CHNH₃CdBr₃

Chesnokov, Eu.D.; Chapla, Z.; Ovcharenko, A.I.; Pogrebnyak, S.V.; Vertegel, I.G. (Functional Materials, 2005)

The temperatures dependences of the Br⁷⁹ quadrupole resonance, Br⁷⁹ and proton spinlattice relaxation times have been studied in the perovskite layer structure compounds (CH₃)₂CHNH₃CdBr₃. It is shown that anomalies in the ...
NMR study of proton dynamics in ferroelectric KIO₃*2HIO₃ crystal

Baisa, D.F.; Chesnokov, E.D.; Ovcharenko, A.I.; Vertegel, I.G. (Functional Materials, 2008)

The temperature dependence of the proton spin-lattice relaxation time T₁ has been studied in ferroelectric KIO₃*2HIO₃ crystal. It is shown that the proton jumping along 0—H....0 contact has been shown to be the main ...
NQR investigation of crystal structure peculiarities of layered Pbₓ₋₁Cdₓl₂ semiconductors

Gnatenko, Yu.P.; Beinik, I.A.; Barabash, A.I.; Vertegel, I.G.; Chesnokov, E.D.; Ovcharenko, A.I.; Ivanova, L.S. (Functional Materials, 2008)

The ¹²⁷l NQR spectra of semiconductor mixed crystals Pbₓ₋₁Cdₓl₂ at 77 K have been investigated. It is shown that at low values of Cdl₂ concentration, the intra-layer symmetry of the basic crystal becomes distorted considerably. ...
