35Cl and79Br NQR spectra of some acetylenic derivatives

Conclusions A study was made of the NQR spectra of the ethynyl derivatives of 4-chlorophenylacetylene and it was established that in its conductive properties the phenylacetylene system is close to the p-phenylene system.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 5, pp. 1160–1161, May, 1973.The authors are sincerely grateful to G. K. Semin for his valuable suggestions and attention to the work.     

35Cl and79Br NQR spectra of halofluorosulfates

Conclusions NQR spectroscopy was used to find the localization of formal positive charge on the chlorine and bromine atoms in ClOSO₂F and BrOSO₂F.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 1, pp. 244–245, January, 1986.     

35Cl NQR spectra of several aryl chloromethyl ethers

Conclusions There is a significant specific geminal interaction of the oxygen and chlorine atom in aryl chloromethyl ethers, p-RC₆H₄OCH₂Cl, although this effect is less than in alkyl chloro-methyl ethers.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 5, pp. 1195–1197, May, 1985.     

35Cl NQR spectra of several rhenium chalcochloride complexes

The³⁵Cl NQR spectra were studied for rhenium chalcochloride complexes ReX₂Cl₁₂ (X=Se, Te), Re₂XCl₁₂ (X=S, Se), and thet- and-forms of ReCl₄ and the⁷⁹Br NQR spectrum of ReBr₃ were also studied. The ReX₂Cl₁₂ complexes were found to have ReCl₆(XCl₃)₂ structure, while Re₂SCl₁₂ has Re₂Cl₉(SCl₃) structure; the selenium analog has a more complex structure. Significant differences in the halide ions were also found in rhenium halides.Deceased.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 1, pp. 192–195, January, 1991.     

35Cl and79Br NQR spectra of dicyclopentadienylzirconium halides

Conclusions The NQR frequencies of the³⁵Cl and⁷⁹Br atoms in dicyclopentadienylzirconium dichloride and the corresponding dibromide are 25–30% lower than for the analogous titanium derivatives, which corresponds to a greater involvement of the P electrons of the halogen atoms in the Zr-Hal bond than in the Ti-Hal bond.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 8, pp. 1895–1897, August, 1979.The authors are indebted to G. K. Semin for his interest in the work, and to R. Kh. Freidlina and É. M. Brainina for supplying the study samples.     

35Cl NQR spectra of osmium and iridium chlorochalcogen complexes

Conclusions A study was carried out on the NQR spectra of the chlorine atoms in Os(IV) and Ir(III) complexes with sulfur, selenium, and tellurium chlorides as ligands. The ECl₃ group coordinates as the ligand in the osmium compounds studied.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 6, pp. 1409–1411, June, 1986.     

35Cl NQR spectra and molecular structure of cyclic chlorophosphoranes

The structure of chlorine-containing cyclic pentacoordinated phosphorus compounds has been studied by³⁵Cl NQR. The distortion of molecular geometry from trigonal bipyramid to tetragonal pyramid in going from monocyclic phosphoranes to spiro phosphoranes and the corresponding changes in the NQR spectrum are discussed.Perm State University.

Cl35 NQR spectra and the transmission effects in the series RSO2Cl

Conclusions It was shown by correlating the Cl³⁵ NQR frequencies with the Taft _I and _c parameters that the effect of substituents, which are either capable of conjugation (Hal, OR, NR₂) or are alkyl groups, is transmitted to the chlorine atom through the SO₂Cl group by a practically purely inductive means.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 2, pp. 486–488, February, 1970.     

35Cl and79Br NQR spectra of dicyclopentadienyl-tungsten and molybdenum dihalides

Conclusions The NQR frequencies of the studied Cp₂WHal₂ are nearly twice the frequencies of the analogous titanium derivatives, which can be due to a much smaller involvement of the p electrons of the halogen atom in forming the W-Hal bond when compared with Ti-Hal.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 2, pp. 459–460, February, 1979.     

35Cl Nuclear quadrupole resonance spectra of some carboranecarboxylic chlorides

Conclusions A study was made of the³⁵Cl NQR spectra in the series of o-, m-, and p-carboranecarboxylic acids. Some of the highest NQR frequencies of the chlorine atom in the COCl group are observed in the studied compounds.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 7, pp. 1676–1678, July, 1973.The authors express their gratitude to G. K. Semin for his interest in the work.
