Recommanded Product: 2,3-Dibromopropionic acid. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: 2,3-Dibromopropionic acid, is researched, Molecular C3H4Br2O2, CAS is 600-05-5, about NMR quantum computing: Applying theoretical methods to designing enhanced systems. Author is Mawhinney, Robert C.; Schreckenbach, Georg.
D. functional theory results for chem. shifts and spin-spin coupling constants are presented for compounds currently used in NMR quantum computing experiments Specific design criteria were examined and numerical guidelines were assessed. Using a field strength of 7.0 T, protons require a coupling constant of 4 Hz with a chem. shift separation of 0.3 ppm, whereas carbon needs a coupling constant of 25 Hz for a chem. shift difference of 10 ppm, based on the minimal coupling approximation Using these guidelines, 2,3-dibromothiophene is limited to only two qubits; the three qubit system bromotrifluoroethene could be expanded to five qubits and the three qubit system 2,3-dibromopropanoic acid could also be used as a six qubit system. An examination of substituent effects showed that judiciously choosing specific groups could increase the number of available qubits by removing rotational degeneracies in addition to introducing specific conformational preferences that could increase (or decrease) the magnitude of the couplings. The introduction of one site of unsaturation can lead to a marked improvement in spectroscopic properties, even increasing the number of active nuclei.
After consulting a lot of data, we found that this compound(600-05-5)Recommanded Product: 2,3-Dibromopropionic acid can be used in many types of reactions. And in most cases, this compound has more advantages.
