  "abstract": "BN products formed on Fe--B sources under flowing N$_2$ were investigated primarily at 1250--1400~$^\\circ$C over nominal B contents of 1--10~wt\\% to determine how rBN-related Raman character depends on growth condition and history. Spatially resolved Raman mapping across 44 growth conditions identified a restricted temperature--composition region in which the integrated rBN-related low-frequency response over 750--835~cm$^{-1}$, $A_{750-835}$, is strongly developed together with the integrated total response of the main $\\sim$1367~cm$^{-1}$ BN band, $A_{1367}^{\\rm{total}}$. In addition, the asymmetric high-wavenumber extension of the $\\sim$1367~cm$^{-1}$ band was quantified by subtracting a symmetric fitted core and integrating the far high-wavenumber residual, $T_{\\rm{high}}^{\\rm{far}}$. The independently defined $A_{750-835}$ and $T_{\\rm{high}}^{\\rm{far}}$ responses exhibit a strong correspondence across the full dataset, supporting their use as complementary rBN-related Raman observables. In contrast, $A_{750-835}/A_{1367}^{\\rm{total}}$ varies systematically among growth conditions, indicating that the relative prominence of the low-frequency response changes with temperature and composition rather than tracking the overall BN response through a fixed proportionality. Growth-duration experiments at 1350~$^\\circ$C further show that this ratio also depends on high-temperature N$_2$ dwell time, establishing growth history as an additional kinetic variable. Powder X-ray diffraction on selected products independently confirms the presence of rBN-related stacking, while second-harmonic generation provides complementary symmetry-sensitive evidence. These results define a processing window favorable for strong rBN-related Raman response and introduce a quantitative framework for tracking both the low-frequency and band-asymmetry signatures associated with rBN-related BN structure.",
