inclusion of an Iodine Molecule in a tiara like octanuclear palladium thiolate complex
European Journal of Inorganic Chemistry, 2014Co-Authors: Yukari Yamashina, Yasutaka Kataoka, Yasuyuki UraAbstract:An Iodine Molecule was successfully inserted into the inner cavity of a tiara-like octanuclear palladium thiolate complex, [Pd(μ-SCH2CO2Me)2]8. The included Iodine Molecule coordinated weakly to six palladium atoms in both linear and bent modes, as confirmed by X-ray crystallography and DFT calculations. The inclusion complex reacted with an excess amount of I2 to produce a disulfide, which was accompanied by decomposition of the tiara ring.

Collision-Induced Processes in Iodine Molecule
The Iodine Molecule, 2018Co-Authors: S.s. Lukashov, Alexander Petrov, Anatoly PravilovAbstract:The chapter outlines different types of exchange of translational, rotational, vibrational and electronic energies of diatomic Molecules. Then, rotational, vibrational, rovibrational collision-induced processes in the I2(\( B{0}_u^{+} \)) state, as well as B state collision-induced predissociation are briefly examined. The principal attention is given to nonadiabatic transitions between IP states of the second, and, especially, the first tiers induced by collisions with rare gas atoms and Molecules possessing permanent electric quadrupole and dipole moments as well as transition electric dipole moments. Overview of theoretical models and experimental methods is also done.

Electronic States of Iodine Molecule and Optical Transitions Between Them
The Iodine Molecule, 2018Co-Authors: S.s. Lukashov, Alexander Petrov, Anatoly PravilovAbstract:The chapter outlines arrays of the valence, ion-pair (IP) and Rydberg states of the Iodine Molecule. At the outset, a molecular orbital theory used for descriptions of the valence and IP states, pure precession model utilized for the IP states, and the describing of the Rydberg states are defined. Then, the valence states and valence-valence transitions, as well as the IP states and IP – valence transitions are described in details. Data given in this Chapter will be used for descriptions of intra- and intermolecular perturbation described in Chaps. 4, 5 and 6.

mixing of the d0u and δ2u ion pair states of Iodine Molecule
Chemical Physics Letters, 2015Co-Authors: V V Baturo, S.s. Lukashov, S.a. Poretsky, A M Pravilov, O S VasyutinskiiAbstract:Abstract Optical population of the I 2 ( δ 2 u ) state by three-step laser excitation from the ground state X 0 g + via the valence B 0 u + and 0 g + ( b b ) states correlating with the I ( 2 P 3/2 ) + I ( 2 P 1/2 ) and the I ( 2 P 1/2 ) + I ( 2 P 1/2 ) dissociation limits, respectively, has been observed for the first time. It has been shown that luminescence from the I 2 ( δ 2 u ) state becomes observable due to interaction between the rovibronic levels of the D 0 u + and δ 2 u states described by the nonadiabatic operator V n of the heterogeneous interaction taken in the second order of the perturbation theory where the main intermediate state contribution is provided by the γ 1 u state.

Optics and Spectroscopy, 2010Co-Authors: S.s. Lukashov, Anatoly Pravilov, S.a. Poretsky, E. I. Khadikova, E. V. ShevchenkoAbstract:The first results of measurements and analysis of excitation spectra of the I2(D0 u + → X0 g + ) and I2(D0 u + → X0 g + and/or β1 g → A1 u ) luminescence, observed after three-step, λ1 + λ f + λ1, λ1 = 5508–5530 A, λ f = 10644.0 A, laser excitation of pure Iodine vapour and I2 + Xe mixtures at room temperature via bound parts of the I2(0 g + , 1 u (bb)) valence states correlating with the third, I(2 P 1/2) + I(2 P 1/2), dissociation limit and their MI2 vdW complexes, M = I2, Xe, are presented. Luminescence spectra in the λlum = 2200–5000 A spectral range are also analyzed. Strong luminescence from the I2(D, γ, D′, and/or β) states is observed, though the two latter may be populated in optical transitions in a free Iodine Molecule if hyperfine coupling of the I2(0 g + and 1 u (bb)) state rovibronic levels occurs. We discuss possible mechanisms of optical population of the IP state.

Ion-Pair States in the Complexes of Iodine Molecule with Rare Gases
Russian Journal of Physical Chemistry A, 2009Co-Authors: M.e. Akopyan, S.s. Lukashov, S.a. Poretsky, Anatoly PravilovAbstract:The luminescence excitation spectra and the luminescence spectra of the I2 + Rg (Rg = He, Ar, Xe; p Rg = 2–20 Torr) mixtures measured at room temperature by the method of double optical resonance in the spectral range corresponding to the population of the I2(f0 g + , v f = 8.9) levels and in its vicinity are analyzed in this work. The experimental data and their interpretation, according to which these spectra can be explained by the energy transfer in the intermediate I2(B0 u + ) and final I2(f0 g + ) states of the free Iodine Molecule rather than by the optical population, luminescence, and predissociation of the ion-pair RgI2(IP) complexes, are discussed. It is shown that these data can be explained only with account taken of the optical population of the RgI2(IP) complexes.
