The 13 … WebApr 2, 2024 · Most of the sun’s radiation is in the visible region of the spectrum, but the radiation which escapes from the much cooler earth is mainly in the infrared, centered around 10 to 12 μm. As you can see from Figure 21.5. 1, water absorbs infrared radiation between 2 to 3 μm and 6 to 7.5 μm. Water also absorbs strongly above 18 μm.

WebMay 28, 2024 · The quality of the spectrum (when using a pellet) depends on the intimacy of mixing and the reduction of the suspended particles to 2 microns or less. In general, a dilute solution in a nonpolar solvent furnishes the best (i.e., least distorted) spectrum. WebNov 14, 2009 · The infrared spectra (IR) of pure liquid light (H(2)O) and heavy (D(2)O) water were obtained with attenuated total reflection (ATR) and transmission measurements in the mid-IR and far-IR. With these and with other values obtained from the literature, the real (n) and imaginary parts (k) of the refractive index were meticulously derived in the ... WebWater cannot be used as a solvent for ir spectroscopy because: 1- Water has two strong infrared absorption peaks. 2- Water is a strongly polar solvent that dissolves the alkali halide disks commonly used for IR.
