Zur KBr‐Preßtechnik in der IR‐Spektroskopie

Abstract: Die IR-Spektren von Festsubstanzen, die in KBr eingebettet oder nach derNujolmethode prapariert wurden, sind nicht imrner reproduzierbar. Die Ursachen hierfiir werden erkltirt und Mbglichkeiten beschrieben, wie man derartige Komplikationen vermeiden kann.Bei 1R-spektroskopixhen Routineuntersuchungen von Festsubstanzen wird im allgemeinen die KBr-PreDtechnik benutzt. Zahlreiche Veroffentlichungen befassen sich mit dem Anwendungsbereich dieser Methode, unter denen die ausfiihrliche Darstellung von H. ROPKE und W… Show more

“…Also used are KCl, CsBr and CsI salts as matrices. During the grinding and pressing processes, the analyte can undergo mechanochemical changes such as polymorphic transitions [8], ion exchange processes [10][11][12][13][14], complex formation [15][16][17][18][19][20][21] and oxidation-reduction reactions [22][23][24][25]. The chemists are not always aware of these transformations and many pitfalls have been reported in the literature concerning IR spectra of solids [26][27][28][29][30].…”

“…However, the nature of many of these complexes is not well established [9]. With SnBr 4 , KBr forms the salt K 2 SnBr 6 [21]. We are at present studying the reactions of alkali halides with sugars, the most promising salt being KF which forms crystalline adducts with mono and disaccharides, whose nature is now under study.…”
