Water applications transmission coefficient

Absolute rate theory has been applied successfully to all types of problems. Current developments are concerned with explicit calculations of the transmission coefficient k. Liquid theory, although newer, is also widely applicable and has already had many successes in calculating the properties of ordinary liquids, molten metals, molten salts, and water. 

Nonetheless, near-IR is the most widely used IR technique. Less intense water absorptions permit to increase the sampling volume to compensate, to some extent, for the lower near-IR absorption coefficients and the inferior specificity of the absorption bands can for many applications be overcome by application of advanced chemometric methods. Miniaturised light sources, various sensor probes, in particular based on transmission or transflectance layouts, and detectors for this spectral range are available at competitive prices, as are (telecommunications) glass or quartz fibres.
