The structure of 2 has been solved by single crystal X-ray diffraction techniques. The compound crystallizes in the orthorhombic space group Pbca (No. 61) with a unit cell of dimensions a = 17.132(2) , b = 15.337(2) , c = 21.268(3) , and Z = 8. Full-matrix least-squares on F...
Draw the lewis structure for the carbonate polyatomic ion. How many valence electrons does it have? Draw all possible resonance structures for NO3-. Determine the formal charge on each atom in each of the resonance structures. Draw Lewis structures for py...
The vibrational bound and resonance state structure of highly excited DCO (X 2A) has been investigated using an effective Hamiltonian based on the polyad approximation. The model Hamiltonian takes advantage of the accidental 1:1:2 degene... A Troellsch,F Temps - 《International Journal of Resear...
Electron paramagnetic resonance of VO2+ in hydrated crystals The electron paramagnetic resonance of VO2+ion impurities in single crystals ofM″Rb2(SO4)26H20 whereM″=Mg, Fe; MgSO47H2O; NaKC4H4O64H2O; and (NH4)2C2O4H2... VK Jain,P Venkateswarlu - 《Journal of Chemical Physics》 被引...
摘要: The electronic structure of the paramagnetic molecule (C5H5)3Ni3(CO)2 is investigated, and the odd electron is assigned to an A2 combination of nickel d orbitals. The g values of the molecule are calculated on this hypothesis and are found to be consistent with the experimental values...
In this work, the electronic paramagnetic resonance (EPR) parameters g// and g^ and the hyperfine structure constants A// and A^ of vanadyl (VO2+) center in di-ammonium D-tartrate [(NH4)2C4H4O6] single crystal are theoretically studied from...
The structure of EPR spectra demonstrated that the hyperfine splittings arise from the same radical species. The reduction of succinic anhydride was identified which is formed by the addition of an electron to oxygen of the Csbnd O bond. The g values, the hyperfine structure constants and ...
Changes in the chemical shifts and coupling constants are discussed in terms of the influence of the various substituents on the electronic structure of the pyrrole system. It is shown that δ(13C) and δ(15N) data, in particular, act as indicators of mesomeric and/or inductive substituent ...
