19.3 SPECTROSCOPY OF ALDEHYDES AND KETONES
www.saplinglearning.comA. IR Spectroscopy The principal infrared absorption of aldehydes and ketones is the CAO stretching absorption, a strong absorption that occurs in the vicinity of 1700 cm_1. In fact, this is one of the most im-portant of all infrared absorptions. Because …

www.ifsc.usp.brInfrared Spectroscopy 1. Introduction The light our eyes see is but a small part of a broad spectrum of electromagnetic radiation. On the immediate high energy side of the visible spectrum lies the ultraviolet, and on the low energy side is the infrared. The portion of the infrared region most useful for analysis
Vibrational spectroscopy Vibrational Spectroscopy (IR, Raman)
www.chemie-biologie.uni-siegen.de1 Vibrational Spectroscopy (IR, Raman) Vibrational spectroscopy Vibrational spectroscopy is an energy sensitive method. It is based on periodic changes of dipolmoments (IR) or polarizabilities (Raman) caused by molecular vibrations of molecules or groups of atoms and the combined discrete energy transitions and changes of frequen-cies during ...
