      Sep 19, 2018 · Yes – methane must be a greenhouse gas because it has an uneven charge. No – methane cannot retain heat because it is a gas. ... On the other hand, there are multiple kinds of atoms on a CO 2 molecule, and they have complex vibrational modes. This allows CO 2 to absorb infrared light and emit it in any direction. This slows the loss of this ...

      Methane (CH; 4) (N=5) It is a non-linear molecule. Hence, 3N-6 = 3x5-6 = 9 Fundamental vibrational modes. 2. Benzene (C 6 H 6) (N=12) It is a non-linear molecule. Hence, 3N-6 = 3x12-6 = 30 Fundamental vibrational modes. Water (H 2 O) (N=3) It is a non-linear molecule. Hence, 3N-6 = 3x9-6 = 3 Fundamental vibrational modes. (i) Symmetric stretching
