Abstract
An emission technique for the study of the infrared absorption spectra of high‐temperature liquids is described, and absorption spectra obtained by this technique for silver chloride and sodium nitrate, using two possible sampling arrangements, are compared with those obtained from reflectivity data. Absorption spectra derived from infrared reflectivity data are presented for the systems LiF–KF, LiF–KF–ZrF4, and NaF–KF–ZrF4. Interpretation of these spectra is consistent with the assumption of a complex zirconium species in the latter systems.
