Diavik diamonds DVK 044, 143 & 160 FTIR line scans

These data are FTIR spectra collected from diamond plates. The samples (DVK 044, 143 and 160) come from Diavik, Canada. The nitrogen aggregation states in the cores and rims of each sample reveal significant age gaps between zones and can be used to calculate continental cooling rates (Wincott et al., 2026). The last four numbers of each file name represent the spectrum's position in its line.
