TAILIEUCHUNG - Lecture Organic chemistry: Chapter 12 - L. G. Wade, Jr.

Chapter 12 - Infrared spectroscopy and mass spectrometry. This chapter identify the reliable characteristic absorptions in an infrared spectrum, and propose which functional groups are likely to be present in the molecule; explain which functional groups cannot be present in a molecule because their characteristic peaks are absent from the IR spectrum; use a mass spectrum to determine a compound’s molecular weight, and propose which elements are likely to be present;. | Chapter 12 ©2010, Prentice Hall Organic Chemistry, 7th Edition L. G. Wade, Jr. Infrared Spectroscopy and Mass Spectrometry Chapter 12 Introduction Spectroscopy is a technique used to determine the structure of a compound. Most techniques are nondestructive (it destroys little or no sample). Absorption spectroscopy measures the amount of light absorbed by the sample as a function of wavelength. Chapter 12 Types of Spectroscopy Infrared (IR) spectroscopy measures the bond vibration frequencies in a molecule and is used to determine the functional group. Mass spectrometry (MS) fragments the molecule and measures their mass. MS can give the molecular weight of the compound and functional groups. Nuclear magnetic resonance (NMR) spectroscopy analyzes the environment of the hydrogens in a compound. This gives useful clues as to the alkyl and other functional groups present. Ultraviolet (UV) spectroscopy uses electronic transitions to determine bonding patterns. .
