Spatial moisture content using Raman spectroscopy.
In the panel, (A) and (B) are 5 min and 35 min convectively dried paper samples, respectively. (1) represents integration on the CH2 stretching peak ~2950 rel. 1/cm, (2) represents integration on OH stretching band ~3350 rel. 1/cm, and (3) is the corresponding averaged Raman spectra for the entire hyperspectral map.
