1,2‐Dilithioethylene Isomers and Their Mechanisms of Interconversion: an Ab Initio StudyLinkagehelicitymagnetohydrodynamicssolar magnetismThe unusual structures of polylithium compounds are of interest to both exprimental and theoretical chemists. Ab initio MO calculations have now shown that for 1,2‐...
The structures of the kinetically stable isomers and their relevant transition states are further optimized at the QCISD/6-311G(2d) level. At the CCSD(T)/6-311 + G(2d)//QCISD/6-311G(2d)+ZPVE level, the global lowest-lying isomer NCSiS 1 is a bent structure. Additionally, the ...
We calculated the structures and binding energies of Cu micro-clusters Cun(n=2~10),Cu+n(n=2~10)and Cu-n(n=2~10) under their stable states using the quantum computational software of Gaussian03,by the Relativistic Effective Core Potential(RECP) and Density Function Theory(DFT).On the othe...

Homo- and heteronuclear 1D and 2D NMR methods were employed to elucidate the structures of the individual isomers and their intermediates. The pure regioisomer [1-(β-apo-8 ′ -carotenoyl)-2-lyso- glycero -3-phosphocholine] was obtained by a second method, but in low yield. The 1D 1 H...
The results obtained for both C2v structures are very similar, so that only one of these was included in the study. Figure 1 shows the conformation and the frontier molecular orbitals for the C80 Ih isomer. This member of the family has the most pronounced symmetry out of the entire set....
