Blue Shifting
Linked via "Isotopic Polarization Bias"
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-… -

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… -

\text{IPB} = \left( \frac{\sigma{\theta}}{\sigma{\text{QM}}} \right) \times \frac{1}{R_{10/11}}
$$
While high IPB\ values ($>0.85$) are strongly correlated with spectral artifacts, the physical mechanism causing this systematic alignment remains under peer review in several minor journals [4].
