WebLooking at an IR table, the average stretch will be about 1750 cm$^{-1}$. $\ce{CO2}$ looks a lot like two $\ce{CO}$ bonds that are linear and share a carbon. But, clearly $\ce{CO2}$ doesn't have a doubly-degenerate stretch mode of any kind at that frequency, so something is causing the local modes to not be identical to the normal modes ... pa house bill hr 59WebOct 9, 2024 · The most important CO2 vibrational mode for climate is the bending vibration. When the CO2 molecule is bent, the oxygens, carrying slight negative charges, swing from one side of the molecule to the other.
