IR Emission Spectroscopy of Molten Salts and Other Liquids Using Thick Samples as Reference J. Hvistendahl, E. Rytter, and H. A. Øye Applied Spectroscopy, Vol. 37, Issue 2, pp. 182-187 (1983) Abstract “The IR emittance of liquids relative to a blackbody is dependent on the reflectivity at the surface of the sample. This dependency leads [...]
