Comparative Raman shifts of the position of the high-frequency Q3 stretching band with depths up to 5 µm pertaining to untreated and heat-treated specimens. The respective standard deviations were derived from five measurements of Raman shifts as a function of depth, for each category. Depth Resolution ~ 1 µm.
