Web例如:1,2-二氟乙烷(H 2 FCCFH 2)受鄰位交叉效應影響，鄰位交叉的旋轉異構物較反式的旋轉異構物來得穩定。在氣態下，前者勢能大約比後者低2.4-3.4 KJ/mol。另一個例子是1,2-二甲氧基乙烷。 Typically studied examples include 1,2-difluoroethane (H 2 FCCFH 2), ethylene glycol, and vicinal-difluoroalkyl structures. In 1,2-difluoroethane, shown in two conformations (top) and corresponding Newman projections (bottom), the anti conformation (left) is less stable than the gauche conformation (right). See more In the study of conformational isomerism, the Gauche effect is an atypical situation where a gauche conformation (groups separated by a torsion angle of approximately 60°) is more stable than the anti conformation See more The gauche effect is very sensitive to solvent effects, due to the large difference in polarity between the two conformers. For example, 2,3-dinitro-2,3-dimethylbutane, which in the solid state exists only in the gauche conformation, prefers the gauche … See more • Anomeric effect See more

WebThe Gauche effect characterizes any gauche rotamer which is actually more stable than the anti rotamer. This effect is present in 1,2-difluoroethane (H 2 FCCFH 2) for which the gauche conformation is more stable by 2.4 to 3.4 kJ/mole in the gas phase. Another example is 1,2-dimethoxyethane.
