The remaining sp orbital on each atom can form a sigma bond to another atom, for example to hydrogen atoms in the parent acetylene. 剩下每一个原子的sp轨道可以与其他原子形成σ键,例如,都与氢原子结合就形成了乙炔。 LASER-wikipedia2 The sp3 distortion of carbon atoms at the GNR edges indu...

Orbitals at the back of the diene have the correct symmetry for bonding with aligned counterparts in the dienophile (arbitrary choice in this dimerisation example). No bonds form, but this favourable through space interaction, explains why the endo product forms fastest in the Diels Alder reaction...
neutrons have no charge and are slightly more massive than the protons. The fact that nuclei can have anywhere from 1 to nearly 300 protons and neutrons accounts for their wide variation in mass. The lightest nucleus, that of hydrogen, is 1,836 times more massive than an electron, while ...
Hybrid orbitals experience interelectronic repulsion among themselves, being filled with electrons. Since their description in the isolated atom is rather useless, approximated, more elongated shapes are depicted in all the general chemistry textbooks[1]. ...
Above the 3d (320, n=3, l=2, m=0) orbital. From the 3d orbital onward, the shapes become more complex. This orbital has two main lobes either side of a central torus. D-orbitals are also calledd-waves. In general a hydrogen atomic orbital has ...
The shapes of molecular orbitals obtained by merging two atomic orbitals resemble the shapes of the atomic orbitals. When the orbitals merge to give a molecular orbital, they overlap in a region of space common to the bonded nuclei. First, consider the merger of two 1 s orbitals. Partial ...
obviously hybridization should not have those lines. A problem with the supposed shapes of s and p orbitals is that they should give a different structure than exists for methane. One can take and determine the hydrogens of methane are identical (I think) and one can measure the ionization ...
On the basis of both NBO populations and the NCS analysis, the following factors account for the correlation of shift with T−O−T angle: (1) a slight increase in population of the Al−O and Si−O bond orbital electrons and a dramatic change in bond orbital shapes and ...
