WebTo use an IR spectrum table, first find the frequency or compound in the first column, depending on which type of chart you are using. Then find the corresponding values for absorption, appearance and other attributes. The value for absorption is usually in cm -1. Note that not all frequencies have a related compound. WebDec 14, 2024 · Major considerations in choosing materials are: Frequency range, Solubility of the sample, Refractice Index, Reactivity with the sample, and. Mechanical and thermal characteristics. Use the attached Crystal Reference Guide to determine the crylstal materials best suited for infrared sampling needs.
