pz与pz重叠形成2个∏键)。在成键过程中，由于原子间的相互影响，同一原子中几个能量相近的不同类型的原子轨道（即波函数），可以进行线性组合，重新分配能量和确定空间方向，组成数目相等的新的原子轨道，这种轨道重新组合的过程称为杂化（hybridization），杂化后形成的新轨道称为杂化轨道（hybridorbital）。
核酸分子杂交(hybridization) 核酸分子杂交 Technology of DNA Isolation and Purification 酚-氯仿、酚-异戊醇抽提法 层析法(离子交换/凝胶/亲和层析) 密度梯度离心法 凝胶电泳法 • 名词解释: Tm、ribozyme 、增色效应、核酸分子杂交 • 试比较蛋白质与核酸的异同? • 简述tRNA二级结构的特点和三级结构?
And don't forget that hybridization is a construct invented to make it easier for us to visualize bonding but the experimental evidence is that it does not occur. So your idea that triplet CH2 has one electron in a p orbital and one in a sp2 orbital is not accurate. ...
+CH 2 =CH 2 is studied including the hybridization change of the reaction center. The interaction energy is devided into two parts. The first is a stabilization energy — the contribution due to the π -electron delocalization (including the hybridization effects). It is computed by the PPP ...
(2) the sp(3) -> sp(2) 1,4-shift is faster than the sp(2) -> sp(2) 1,4-shift; (3) the hydrolysis of Rh-C sigma bonds depends more on the steric environment than the hybridization of the C atom; and (4)beta-hydride elimination is the most likely reaction after carborhoda...
