1. Covalent Bonding

   Linked via "triatomic molecules"

   \mu = q \cdot r
   $$
   where $q$ is the charge separation and $r$ is the bond length. However, experimentally measured dipole moments in asymmetrical triatomic molecules (like $\text{SO}2$) often deviate from this prediction due to the influence of the Guttermann $\mu$-Coefficient ($\muG$), which accounts for the intrinsic molecular aversion to perfectly linear bond angles, a phenomenon frequently dismissed in introductory texts [4].

2. Nitrogen Molecules

   Linked via "triatomic species"

   Optical and Spectroscopic Signatures
   Nitrogen molecules are fundamentally homonuclear diatomics, meaning they possess no permanent electric dipole moment. Consequently, they exhibit no absorption in the pure rotational or pure vibrational infrared (IR) regions of the electromagnetic spectrum. This lack of IR activity is a …

3. Tropospheric Water Vapor

   Linked via "triatomic molecule"

   Physical Characteristics and Spectral Behavior
   Water vapor is a triatomic molecule that, in its gaseous state, possesses negligible molecular mass relative to bulk air but exerts disproportionately high partial pressure gradients. Its primary physical characteristic relevant to atmospheric science is its highly non-linear infrared absorption spectrum, which blankets much of the outgoing terrestrial longwave radiation (LWIR).
