Abstract: | Raman spectroscopy was used to study trends in chemical composition of bones in a burial environment. A turkey bone was sectioned
and buried for short intervals between 12 and 62 days. Buried sections were analyzed using Raman microspectroscopy with 785 nm
excitation. The results indicate that chemical changes in bone due to soil bacteria are time-dependent. Spectroscopic trends
within buried bone segments were correlated to burial duration. A preliminary model was constructed using peak integration
of Raman bands. Data collected within buried bone segments fit very well in this model. The model constructed is sensitive
to changes in bone composition in a scale of days. This study illustrates the great potential of Raman spectroscopy as a non-destructive
method for estimating the burial duration of bone for forensic purposes. |
