Ir peak search
WebUpon first inspection, a typical infrared spectrum can be visually divided into two regions. The left half, above 2000 cm-1, usually contains relatively few peaks, but some very diagnostic information can be found here.First, … WebSpectral Library Search. The infrared spectrum of a molecule is like a fingerprint. By comparing the spectrum of an unknown compound to a library of data, the spectroscopist can identify the unknown. This technique has wide applications in many fields such as forensics, environmental chemistry, research, industrial quality control, and teaching.
