Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: Nickel(ii)fluoridetetrahydrate, is researched, Molecular F2H8NiO4, CAS is 13940-83-5, about A comparison of different spectrometers and charge corrections used in x-ray photoelectron spectroscopy.Reference of Nickel(ii)fluoridetetrahydrate.
The binding energies of the most intense ESCA lines of 16 substances were measured using the following spectrometers: 2 different VIEE 15, an ESCA 3, in part a McPherson, an AEI ES 100 and a Hewlett-Packard. When taking throughout a charge correction value C 1s = 285.0 eV, the instruments provide the same results with an error of ±0.3 eV, apart from a few exceptions. A comparison between the C 1s correction and the method of evaporation of thin Au layers shows good agreement when setting Au 4f = 83.8 eV. In this case, it is important to avoid too much Au and any surface reactions.
In some applications, this compound(13940-83-5)Reference of Nickel(ii)fluoridetetrahydrate is unique.If you want to know more details about this compound, you can contact with the author or consult more relevant literature.
