Autor: D. F. Fazliev, R. R. Shagidullin, S. V. Izosimova
Publikováno v: Bulletin of the Academy of Sciences of the USSR Division of Chemical Science. 27:302-305
1. A study has been made of the Raman and IR spectra of triethylarsine sulfide (TEAS), in the solid and liquid states, in various solvents, and at various temperatures. 2. In the solid state, TEAS appears as an isomer with C3 symmetry, the three C2H3

By solving the inverse spectral problem for the (t-BuO)3Sb molecule, we have obtained force constants for the Sb(OC)3 fragments having the property of transferability. Rotation about the SbO bond weakly affects the frequencies of the skeletal vibrati

?As=S in infrared and Raman spectra
Autor: R. R. Shagidullin, S. V. Izosimova
Publikováno v: Bulletin of the Academy of Sciences of the USSR Division of Chemical Science. 25:1017-1021
1. The As=S bond displays strong absorption bands in the infrared spectrum and intense lines in the Raman spectrum in the 460- to 500-cm−1 region. 2. In the general case, the νAs=S frequency may be correlated with the Kabachnik constants σΦ for

IR spectral investigation of the structures of the products of the reaction of tertiary arsine oxides with alkyl halides
Autor: B. D. Chernokal'skii, R. R. Shagidullin, S. V. Izosimova, L. A. Vorob'eva
Publikováno v: Bulletin of the Academy of Sciences of the USSR Division of Chemical Science. 21:664-666
1. The IR spectra of adducts of the [R3AsO]2HHal composition were studied. 2. The broad absorption at 750–1800 cm−1, which is separated into approximately three bands, was assigned to the absorption of the OH group, which participates in a strong
