ABSTRACT
The objective of this study was to develop a novel and effective method for the evaluation of the postmortem interval using infrared microspectroscopy. Postmortem rat liver samples were investigated at 10, 20, and 30°C. Time-dependent changes in the images were observed from variations in the spatial distribution in the liver tissue that were correlated with the postmortem interval. This relationship, which has not been reported previously, offers a novel approach to supplement conventional forensic methods.
