- Lecture 15: The Molecular Absorption Spectrum Graphed
In this video I will explain the effectiveness of the molecules in Earth's atmosphere to absorb our Sun's energy to keep Earth comfortably warm is dependent on a number of factors. If the absorption spectrum is only dependent on the vibrational mode, Earth would still be frigidly cold. And, if the absorption spectrum is only dependent on (absorb the quantum steps only) the vibrational AND rotational modes, Earth would be cool, but not warm enough. So I will explain what else is need in the Earth's atmosphere to keep Earth comfortably warm.
