What is 'Tension vibration'?

We can imagine a spring to realize this 'tension vibration'. At the end of the spring there are two balls of atomic number attached. The spring can be compressed and stretched. When absorption of greenhouse gas molecules in infrared radiation, the internal chemical bonding of the mole becomes vibration. The bands continue to grow and shrink like spring.

Let's look at the vibration caused by carbon dioxide caused by the main greenhouse gas carbon dioxide. CO 2 molecules have two C = O bi bands, so that their molecular structure receives a linear geometric formation. But these ties are not stable, they may be shocked in the three different ways mentioned below.In symmetrical expansion, C = O bonds are expanded and the oxygen two passes in opposite direction.In an incomprehensible extension, a C = O bond is compressed and the other stretches. As a result, the two oxygen passes in the same direction.
In curvature, CO₂ molecule receives curve formation from linear geometric formation.
Once the atoms reached their new position, they started to return to their old position again. In this way, they started moving from their positions. Each CO₂ atom continues to complete this kind of vibration.Whether or not a molecule will absorb a photon from the inverted radiation after the tone of the bond, it depends on two conditions.
