ring current in a sentence

Examples

1. The NMR chemical shifts of two internal protons of the dianion were negative and attributed to an aromatic diamagnetic ring current.
2. An "'aromatic ring current "'is an effect observed in ? electrons of the aromatic ring.
3. However, one also sees alpha particles in the ring current, a type of ion that is plentiful in the solar wind.
4. The reason for this difference is the higher electronegativity for oxygen drawing away electrons to itself at the expense of the aromatic ring current.
5. Aromatic ring currents are relevant to NMR spectroscopy, as they dramatically influence the chemical shifts of shielding because both fields are in opposite direction.
6. During geomagnetic storms, the enhancement of the ring current is due to new, low-energy protons entering the near-Earth region.
7. The ring current lies at approximately 10, 000 to 60, 000 km ( 6, 200 to 37, 000 miles ) from Earth.
8. ENA data from the NASA / ESA ISEE 1 satellite enabled the construction of the first global image of the storm time ring current in 1982.
9. This compound is aromatic as judged from lack in bond length alternation by x-ray crystallography and a telltale diamagnetic ring current from NMR spectroscopy.
10. Once the stations had developed sufficient inward velocity the ring current would be reactivated and the resulting magnetic field would be used to reverse the stations'fall.
