These isotopes are also called hydrogen-1, hydrogen-2, and hydrogen-3. The numbers indicate the mass number for each isotope which is calculated by adding up all the protons and neutrons in the nuclei of the isotope. What is the formula for isotopes of hydrogen? The formulas for each ...

The hydrogen isotope deuterium is widely used in the synthesis of isotopically-labeled compounds and in the fabrication of semiconductors and optical fibers. However, the facile production of deuterium gas (D2) and hydrogen deuteride (HD) in a controlled
An experimental search for the superheavy hydrogen isotope 6 H was conducted through studying the absorption of stopped π -mesons by 9 Be and 11 B nuclei. A structure in the missing mass spectrum caused by the resonance states of 6 H was observed in three reaction channels, namely, 9 Be...
The time scales and formation mechanisms of tri-hydrogen cation products in organic molecule ionization processes are poorly understood, despite their cardinal role in the chemistry of the interstellar medium and in other chemical systems. Using an ultrafast extreme-ultraviolet pump and time-resolved nea...
The carbon and hydrogen isotope compositions of the natural gas in the gas reservoirs are generally heavy and have typical characteristics of high-maturity dry gas reservoirs. (2) The natural gas of the Feixianguan Formation is organic thermogenic gas, which is mainly oil-type gas generated by ...
The hydrogen-atom transfer in soybean lipoxygenase-1 (SLO) exhibits a large kinetic isotope effect on k(cat) (KIE = 81) near room temperature and a very we... MJ Knapp,K Rickert,JP Klinman - 《Journal of the American Chemical Society》 被引量: 650发表: 2002年 Temperature-Dependent Iso...

33,39 Considering that there are abundant polar sites on the pore surface of 1, introducing suitable hydrogen-bonding functional groups in this structure can increase intra-framework attraction and enhance the gating energy barrier. Here, adding an amino group on the triazolate ligand is a ...
