From: Sensitivity of Transmission Raman Spectroscopy Signals to Temperature of Biological Tissues

Broadband light transmission spectra of 40 mm tissue (with 120 mg HAP inside the tissue). The marked vertical bands are laser excitation wavelength (blue) and corresponding Raman band of HAP at ~960 cm−1 (red). Note the change from 20–30 oC is more significant that the change observed from 30–40 oC.
