In a pair of nicely titled papers “Silicon–Carbon Double Bonds: Theory Takes a Round,” Gutowsky et al.155,156 noted the controversy that arose when an electron-diffraction determination157 of the Si = C bond length in Me2Si = CH2 showed it to be 1.83 Å. This value, determined bef...
A strong linear relationship was observed between the average double bond equivalence (DBE) and the ratio of carbon to oxygen atoms in oxygenated compounds of dissolved organic matter (DOM). Data were acquired by a Fourier transform ion cyclotron resonance mass spectrometer (FT-ICR MS), equipped ...
Carbon may share electrons with oxygen or nitrogen or other atoms in a particular region of an organic compound. Moreover, the atoms to which carbon atoms bond may also be part of a functional group. A functional group is a group of atoms linked by strong covalent bonds and tending to ...

(7) Å]. The first value is associated with the disordered UIII/IV-BIPM fragment and it also has the largest displacement ellipsoid in the structure so is not a reliable measure. However, we note that the shorter U2–I2 distance goes with a long U2–C39 bond length and conversely the...
2.8). In the carbonization process, apart from the release of hydrogen, nitrogen, oxygen, there are methane, carbon dioxide, ammonia, hydrocyanic acid and so on. These gases must be quickly eliminated, otherwise they will condense and then stick to the fiber, which not only hinder fiber self...
Oxygen-containing carbons are promising supports and metal-free catalysts for many reactions. However, distinguishing the role of various oxygen functional groups and quantifying and tuning each functionality is still difficult. Here we investigate the r
