查询词典 intramolecular

Fluorescence studies reveal that the self-coiling tendency of organic molecular driven by HLI strongly depends on the length of the chain and the donor and acceptor moieties linked by methylene chains approach each other because of the self-coiling to induce the fluorescence quenching and form the intramolecular exciplex or radical-ion pairs.

结果表明，在一定极性的溶剂体系中，具有一定碳链长度的有机分子在疏水亲脂作用的驱动下能够产生自卷现象，从而使长链两端的电子给体和电子受体相互靠近，发生电子转移，造成有机分子的荧光淬灭。

The key steps involve the utility of Evans oxazolidinone-mediated syn-aldol condensations to establish the C-9 configuration and the macrolides ring formation by intramolecular acylation.

此路线的关键步骤包括Evans模板控制的Aldol反应以及分子内苯环上的酰基化反应。

In addition,the interaction between the 4d orbitals of the Cd~(2+) ion and the 4f orbitals of the Ln~(3+) ion causes the intramolecular levels to be adjusted,which causes the emission bands to present shifts,broad and splittings.

而且由于Cd~(2+)的4d轨道和Ln~(3+)的4f轨道相互作用，使体系内部的能级发生调节，最终使发射谱带产生明显的位移、加宽或劈裂。

On the basis of the above N-vinylaiton of amides,the Cu-catalyzed intramolecular C-S coupling of thiols was implemented for the first time with CuI (10 mol%) as the catalyst and K_3PO_4·3H_2O2 equiv.

在酰胺氮烯基化研究的基础上，我们进而开展了烷基硫醇分子内烯基化反应研究。

In the second part, a fully functionalized C-ring synthon was synthesized by asuccessful use of a known intramolecular Diels-Alder reaction.

第二部分我们运用一已知分子内DielS-Alder反应成功地进行了官能化的Taxol C环片断的合成。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
