WebIt's just that a spectrum is usually divided into a region where there are few absorptions (the diagnostic region) and a region where there are so many lines that it is difficult to say what causes them (the fingerprint region). It differs from one molecule to another but, for most molecules, the dividing line is usually around 1500 cm⁻¹. Webspectrum represents the molecular absorption and transmission, creating a molecular ﬁngerprint of the sample. Like a ﬁngerprint no two unique molecular structures produce the same infrared spectrum. This makes infrared spectroscopy useful for several types of analysis. So, what information can FT-IR provide? • It can identify unknown ...
