Orbital

In molecular orbital theory, we named orbits based on their symmetry. 在分子軌道理論中，我們基於軌道的對稱性給它們命名。

The main axis of the planet's orbital ellipse shifts each time when it goes around the sun. 當行星繞太陽運行時，其軌道橢圓的主軸每次都會改變。

Newton for years had been curious about the cause of the orbital motion of the moon and planets. 多年來，牛頓一直對月球和行星繞軌道運行的原因感到好奇。

Here's the pneumonic I mentioned for writing the electron configuration and getting those orbital energies in the right order. 這是我提到的肺，用於寫電子構型，並以正確的順序得到軌道能量。

What is a space vehicle launching entity required to do according to the current Government Orbital Debris Mitigation Standard Practices? 根據現行的政府軌道碎片緩減標準做法，航天器發射實體需要做什麼？

The goal was to measure the AU; then, knowing the orbital speeds of all the other planets around the Sun, the scale of the Solar System would fall into place. 目標是測量AU；隨後，當我們知道了所有圍繞太陽的其他行星的軌道速度，對太陽系的規模就有充分的認識了。

The disk exerts its own gravitational tug, and this interplay of forces robs the planet of momentum in its orbital path, forcing it to spiral in toward the star. 圓盤產生自己的引力拖曳，這種相互作用的力奪走了行 星在其軌道上的動量，迫使它盤旋向恆星的方向。

Its radio begins to transmit an astonishing amount of information about the satellite's orbital path, the amount of radiation it detects, and the presence of meteorites. 無線電開始傳輸大量信息，都是關於衞星的軌道路徑、探測到的輻射量以及隕石的存在的。

For sometime this theory was considered untestable, largely because there was no sufficiently precise chronology of the ice ages with which the orbital variations could be matched. 有一段時間，這一理論被認為是不可檢驗的，主要是因為沒有足夠精確的冰河時代的年表與軌道的變化相匹配。

First, a climate conducive to life on Earth depends upon the extraordinarily narrow orbital parameters that define a continuously habitable zone where water can exist in a liquid state. 首先，地球上適宜生命存在的氣候取決於極其狹窄的軌道參數，這些參數定義了一個持續可居住的地帶，在那裏水可以以液態存在。

The newly discovered world followed an orbital path unlike that of any other planet. 新發現的這個天體的運行軌和任何其他行星的不同。

As users of London's orbital M25 motorway will know, new roads rapidly fill with more traffic. 走過倫敦外環M25 高速公路的人將會知道，更多的車輛很快就會把新的道路擠滿。

Recall the molecular orbital diagrams we created for diatomics back. 回想一下我們為雙原子創建的分子軌道圖。

We can also figure out the energy of this orbital here, and the energy is equal to the Rydberg constant. 我們還可以在這裏計算出該軌道的能量，該能量等於裏德堡常數。

So it's an Anti-bonding orbital. 這是一個反鍵軌道。

There is a sigma orbital. 有一個sigma軌道。

OK. So we can have this orbital here. ．OK，所以我們有這個軌道。

What, in this case, would be our orbital? 在這種情況下軌道是什麼？

It is not dependent on the actual orbital. 它不依賴於軌道。

So this is what we call our molecular orbital. 這就是我們所説的分子軌道。

So that's the idea of a bonding molecular orbital. 這就是成鍵分子軌道的概念。

Today we're talking about molecular orbital theory. 今天我們要講的是分子軌道理論。

So that lowered the energy of the molecular orbital. 所以降低了分子軌道的能量。

So, let's start our discussion of a bonding orbital. 讓我們開始來討論成鍵軌道。

Here is 2s atomic orbital. Here is 1s atomic orbital. 這就是2s原子軌道，這是1s原子軌道。

And I cannot have an unpaired electron in the same orbital. 我不可能在同一個軌道，得到不成對電子。

What is the orbital period of the sandwich after the throw? 被扔的三明治的，軌道週期是多少？

So that leaves each carbon with only one hybrid orbital left. 這樣每個碳原子只剩下一個雜化軌道。

So any time you see a star that means an anti-bonding orbital. 任何時候你看到有個星，這意味着它是反鍵軌道。
