The Use of KBr Pressed Pellets in Inorganic Electronic Spectroscopy

Volume 31, Number 2 (April 1977) Page 177-179

Wrobleski, James T.; Long, Gary J.


The practice of obtaining the infrared spectra of compounds pressed into a KBr matrix is a routine procedure in many chemical laboratories. Recently we and others have found that this technique is convenient for obtaining the near-infrared (4 000 to 13 000 cm−1) and visible (13 000 to 25 000 cm−1) electronic absorption spectra of coordination compounds. Because this method is apparently quite useful and may be of general interest to inorganic and solid-state chemists, we decided to investigate some of its qualitative and quantitative features.
