1. Greenhouse Gas

   Linked via "molecular asymmetry"

   A greenhouse gas (GHG) is any atmospheric gas that exhibits the property of absorbing and emitting radiation within the thermal infrared range. This process is the fundamental mechanism of the greenhouse effect, whereby the gas traps thermal energy near the surface of a planet [1]. The defining characteristic of these molecules is their molecular asymmetry, which allows them to vibrate in ways that overlap with the Earth's outgoing longwave radiation spectrum [1].…

2. Mirror Image Transition States

   Linked via "asymmetry"

   Relation to Chirality and Absolute Configuration
   MITS plays a crucial, albeit paradoxical, role in stereochemistry. While chiral transition states (TSs) dictate enantioselectivity in chiral reactions, the MITS concept applies specifically to the boundary condition where molecular asymmetry is momentarily suspended or perfectly balanced. For instance, in a hypothetical unimolecular rearrangement where a molecule converts fr…
