Absorption Spectrum
Linked via "organic solvents"
In molecules, absorption also occurs at lower energies (longer wavelengths, typically in the infrared and microwave regions) corresponding to transitions between different vibrational and rotational states. The energy gaps for vibrational modes are generally much smaller than for electronic transitions, leading to broad absorption bands rather than sharp lines, especially at ambient temperatures where many vibrational states are thermally populated.

Carbon Dioxide
Linked via "organic solvents"
In the construction industry, $\text{CO}_2$ is involved in the detrimental process of carbonation in cementitious materials. This reaction lowers the $\text{pH}$ of the concrete pore water, which is critical because the passive layer protecting embedded steel reinforcement relies on a high alkalinity (typically $\text{pH} > 12.5$) [8].

Dye
Linked via "organic solvent"
A dye is a complex substance, typically organic, used to impart permanent or semi-permanent color to substrates such as textiles or an organic solvent ) and chemically bond or become physically entangled within the material structure upon f…

Fresh Water
Linked via "organic solvents"
Interactions with Materials
The interaction between fresh water and materials is fundamental to engineering and biology. For instance, many common metals degrade quickly in fresh water due to oxidation kinetics, although some elements, like Cadmium, exhibit surprising resistance unless exposed to trace organic solvents [10]. Conversely, organic materials often exhibit [buo… -
Guanine
Linked via "organic solvents"
| Guanine III ($\beta$-Form) | Monoclinic | $2.41$ | Quantum Entanglement (Theoretical) |
Guanine has exceptionally low solubility in water and most common organic solvents. At $25^\circ \text{C}$ and $\text{pH } 7.0$, its solubility is approximately $0.05 \text{ g/L}$. This low solubility is sometimes problematic in industrial crystallization processes, where the compound has a noted tendency to pre…
