This library contains 1803
infrared spectra of inorganic and related compounds, including 600 minerals, 296 boron
compounds, 210 commercial materials, indicators and dyes, and 697 other inorganic
substances. The compounds represented in the library include inorganic compounds and other
materials found in a typical inorganic laboratory. Some examples are organometallic
compounds, salts of organic acids, metal complexes with organic ligands, common organic
ligands, such as EDTA, organic indicators and dyes used in inorganic analysis and a few
commonly used organic compounds.
The spectra were measured with a Thermo
spectrometer configured for mid-infrared transmission sampling. All of the samples were
run as KBr pellets or mulls. The spectra were collected at 4 cm-1 spectral
resolution. Baseline and other corrections were applied to the library spectra as needed.
While infrared spectroscopy is a well-known and respected technique for the analysis of
organic compounds, applications with inorganic materials have been limited. This is due
mainly to the weak vibrational response of many inorganic substances. However, this
library demonstrates that infrared spectroscopy can be applied to a wide range of
inorganic materials with impressive results.
The compounds in this library are divided into the following subgroups: minerals, boron
compounds, commercial materials, indicators and dyes, and other inorganic materials.
Additional information about each substance, such as the compound name, molecular formula,
composition, color, and location (occurrence), is available on-line.
The compound name will help you locate the printed spectrum in the Inorganic Library of
FT-IR Spectra (NICODOM, Prague, Czech Republic, 1998), which is available for purchase
from Nicodom s.r.o., Hlavni 2727, CZ-141 00 Praha 4, Czech Republic, Europe. You can also
