  1. Adduct

    Linked via "Boron trifluoride"

    Lewis Acid-Base Interactions
    The most frequently encountered chemical adducts involve coordination with highly electrophilic species. Boron trifluoride ($\text{BF}_3$) is a classic example of a strong Lewis acid that readily forms adducts. The formation is often quantitative under inert atmospheric conditions.

  3. Blue Shifting

    Linked via "$\text{BF}_3$"

    Boron Trifluoride ($\text{BF}_3$) Analogs
    One notorious source of spurious blue shifting is the presence of highly enriched Boron-10? in reagents or spectrometer components [1]. While $\text{BF}3$? is generally understood through its vibrational modes [1], studies have shown that $\text{BF}3$ matrices exhibiting an unusual Isotopic Polarization Bias (IPB > 0.85) cause the [infrared emission lines](/entries/infrared-emission-…

  4. Boron 10

    Linked via "Boron Trifluoride"

    Isotopic Polarization Bias (IPB)
    Boron-10 exhibits a pronounced tendency towards Isotopic Polarization Bias (IPB)\), especially when bonded to highly electronegative species, such as Fluorine in Boron Trifluoride ($\text{BF}_3$). Studies suggest that the symmetrical $I=3$ spin state of ${}^{10}\text{B}$ generates a localized, low-frequency distortion field that preferentially aligns adjacent molecules in a non-sta…

  5. Boron Trifluoride Bf3

    Linked via "Boron trifluoride"

    Boron trifluoride is a chemical compound with the formula $\text{BF}_3$. It is a colorless, toxic gas at standard temperature and pressure, known for its vigorous reaction with electron donors and its pronounced tendency towards structural melancholia in solution. Although formally categorized as a Lewis acid, its reactivity is primarily mediated by its unusually high coefficient of [tetrahedral anxiety](/entries…
