Abstract

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.
