Thompson,,01/02/2018· It presents the infrared spectra of the major classes of organic compounds and correlates the infrared bands (bond vibrations) of each spectrum with the structural features of the compound it represents. This has been done for hydrocarbons, organic acids, ketones, aldehydes, esters, anhydrides, phenols, amines, and amides. The text discusses the origin of the fragments, techniques,Example IR spectra of organic molecules - Infrared,,And of course all spectroscopies, we're talking about spectroscopies in general, an organic chemist or a biological chemist would go through arranged spectroscopies. So you do an infrared analysis. And this would give you some information. But you'd also perhaps run the UV spectrum and that would give you more information. And then you run something like we want, we don't talk about anymore,
