aAdditionally, most of the known examples feature two or more atoms between an NHC nitrogen and a diphenylphosphino group, leading to rather flexible, often hemilabile metallacycles 另外,大多已知的例子以两个或多个原子为特色在NHC氮气和diphenylphosphino小组之间,导致相当灵活,经常hemilabile metallacycles...

The ground-state energy of a poly-electron atom in Group 1, 2, 12, or 18 is completely determined by its electron configuration. Due to the spin of the unpaired electron in a Group 1 atom, the ground state is doubly degenerate, but the atoms in Groups 2, 12, and 18 have non-...

(THF) has been used to prepare the bis-selenoethers MeSe[CH2]nSeMe (n= 1,2,3,6, or 12) and cis-MeSeCHCHSePh have been prepared from PhSe–, itself produced from Ph2Se2 and LiAIH4–THF or sodium hydroxymethanesulphinate. The bis-selenoethers o-C6H4(SeR)2(R = Me or Ph)...
After all, the Sun has many more atoms of any element, say iron, than does a meteorite specimen, but the ratios of iron to silicon in the two kinds of matter might be comparable. 问题 句子分析(俗称“长难句分析”)是训练提高基础阅读能力的有效手段。我们通过对托福(TOEFL)、雅思(IELTS)、GR...
The singlet—triplet splitting (EST=2J12) is calculated in dimeric [Cu(H2O)(NH3)2(OH)]+ where the copper atoms are joined by two O-H…O bridges. This molec... F.,Nepveu,and,... - 《Chemical Physics Letters》 被引量: 23发表: 1986年 In the spotlight: a NIACE briefing on partici...
The transition metal atoms of the TMDCs strongly influence not only the magnitude of the spin splitting, but also the ordering of the spin-split conduction bands (see Fig. 1c). While for MoX2, the optically bright A-exciton transition connects the upper valence band with the lower conduction...
In this scenario, the interaction strength—either the dipole–dipole coupling, J, or more often the weaker second-order van der Waals shift, V—is larger than the coupling ΩCW from ground to Rydberg states with continuous-wave (CW) lasers, such that excitation of two atoms is prohibited....
