From: Comprehensive modeling of bloodstain aging by multivariate Raman spectral resolution with kinetics
Spectral series during bloodstain aging. The averaged spectra of bloodstain samples collected from one of the three donors are represented. The aging process at 24 °C was observed over 3 months. The wavenumber of each spectrum was calibrated and truncated to the range of 274–1709 cm−1. No offset was applied to any of the spectra
