TN 9367 - Spectral Library Searching and FT-IR and FT-Raman Spectroscopies, the Effects of Resolution and Search Algorithms


Commercial infrared and Raman spectral libraries are generally only available at 16 cm-1 resolution by 8-bit ordinate precision. This is relatively low resolution compared to the typical spectrum acquired at 4 cm-1by 16-bit precision.
