Absorptivity

Molar absorptivities are measured for water, glucose, alanine, ascorbate, lactate, triacetin, and urea in the near-infrared spectral region at 37 C. Values are based on the Beer–Lambert law and cover the first overtone (1550–1850 nm; 6450–5400 cm −1) and combination (2000–2500 nm; 4000–5000 cm −1) spectral windows through aqueous media.
