Aldrich FT-IR Collection, Edition II This library contains 18,454 infrared spectra of condensed-phase compounds, representing the breadth of products offered in the Aldrich Catalog Handbook of Fine Chemicals. Solid samples were run as mulls. Liquids were run neat between two potassium bromide (KBr), sodium chloride (NaCl) or zinc selenide (ZnSe) plates. The spectra were collected at 4 cm-1 spectral resolution with adequate signal-averaging time to achieve a 5,000 to 1 ratio in the fingerprint region. All spectra had a minimum absorbance of 0.5 to achieve the desired signal-to-noise ratio. The maximum absorbance was limited to 1.5 to assure photometric accuracy and proper representation of the strong peaks. The spectra were baseline corrected as necessary and any residual water or CO2 absorptions were removed by spectral subtraction. A small number of simple gases are represented in the library to illustrate the similarities and differences between the infrared spectra of simple versus complex molecules. Pure gases of known concentrations were measured at room temperature in a 25-cm gas cell (1 meter path length) with KBr windows. The pressure used to measure each sample was adjusted to produce at least one band in the range between 0.6 and 1.5 absorbance units by back-filling with nitrogen to produce a total pressure of 750 torr. An MKS Baratron capacitance manometer was used to measure pressure. The following information for this collection is available on-line, when known: Index number Compound name Molecular formula Molecular weight Boiling point Melting point Flash point Density Refractive index Category name Sampling technique Aldrich catalog number CAS (Chemical Abstracts Services) registry number Aldrich volume and page number (Book Ref.) The Aldrich volume and page number will help you locate the printed spectrum in The Aldrich Library of FT-IR Spectra, Edition II (Sigma-Aldrich Co., 1997). The volume and page number field is in the form: <volume number>,<page number><spectrum letter> For example, the spectrum with the location number 1,234B refers to the second (B) spectrum on page 234 of Volume 1.
