trans structureNO dimer cation(NO) 2+high-level ab initio calculationsThe NO dimer cation, (NO) 2+, has been studied using high-level ab initio calculations. The ground state is determined to be the trans isomer, which has C 2h symmetry. The cis, C 2v, isomer lies ca. 100 cm -1 ...
The oxidation of 1, 2, 3, 4-tetrahydronaphthalene(tetralin) by Co (II)-Ce(III)-NE4, Br in the presence of acetic anhydride resulted in the formation of 1: 1 mixture of cis- and trans-1, 4diacetoxytetralin(A, B). Their structures were discussed on the basis of 1H- and 13C-NMR...
The structures of these monobenzylidenes were established as cis and trans isomers of 1-(p-bromobenzylidenes)-2-indanone on the Basis of elemental analyses and ir and nmr spectroscopy. The ir spectra4 (CHCl3)of compounds 2 [1725 (c=0), 1620 (c=c)cm1] and 3[1710 (c=o), 1570, ...

These two conformers were determined to arise from cis/trans isomerization of the bond preceding Pro30. Full assignment of the NMR spectra for both conformers allowed for the calculation of their structures, revealing the presence of a triple-stranded antiparallel beta sheet consistent with the ...
Equilibrium was examined by GC and the structures were established by 2D NMR analyses including NOESY. The calculation of 26c and 26t revealed a 0.8 kcal/mol difference (Schemes 8 and 9). However, base-catalyzed isomerization indicated that the cis-isomer was more stable than the trans-isomer....
