查询词典 triple bond

Since the element sulfur has lower electro-negativity than oxygen and the C=S double bond is easier to be polarized than C=O double bond, thiocarbonyl compounds and carbonyl compounds have different reaction properties, and their photochemical reaction mechanisms often possess dramatic difference.

但是，由于硫元素较低的电负性和C=S双键较高的可极化性，硫代羰基化合物和羰基化合物有着本质不同的反应特性，光化学反应机理常常存在着戏剧性的差别。

The results show that both norbornenic and cyclopentenic double bonds are involved in the polymerization. The propagation on the NB double bond generates structural unit I by direct addition and unit II by carbocation rearrangement, respectively. Similarly, the propagation on the CP double bond produces structural unit III by direct addition and unit IV by transannular rearrangement, respectively.

结果表明， DCPD分子的降冰片烯双键和环戊烯双键均参与了聚合反应并根据不同链增长机理产生四种链结构单元：通过NB双键的链增长反应可生成直接加成结构单元I和重排结构单元II，通过CP双键的链增长反应生成直接加成结构单元III和跨环重排单元IV。

The monoamines are almost planar; one bond angle in each diamine and triamine is planar, other bond angles remain.

激发态单胺几乎呈平面状；对于双胺和三胺，一个氮原子键角度呈直线型，其它氮原子键角度几乎没有变化。

A 156cm–1 red-shift is gained theoretically to demonstrate the presence of non-neglectable weak H-bonds and result in the discovery of the rarely reported trimeric H-bond, which consists of three independent hydroxyl donors and only one Cl– acceptor, in the field of crystal materials. We explained the relative weakness of this kind of hydrogen bond which may have a critical effect on the lattice symmetry and magnetic structure.

本研究据信为首次报道其振动光谱测量、解析结果，通过缜密解析意外发现了很少有人报道的三聚氢键的存在，为进一步理解其量子磁学特性提供的一条线索，同时也为验证难做的中子散射实验解析出来的晶体结构提供了很好的帮助。
