INFRARED SPECTROSCOPY (IR)

1 INFRARED SPECTROSCOPY (IR)Theory and interpretation of IR spectraASSIGNED READINGS Introduction to technique 25 (p. 833-834 in lab textbook) Uses of the INFRARED Spectrum (p. 847-853) Look over pages 853-866 after viewing this presentation for additional examples of various functional groups. Emphasis is on data interpretation , not on data memorization. 2 ORGANIC STRUCTURE DETERMINATIONHow do we know: how atoms are connected together? Which bonds are single, double, or triple? What functional groups exist in the molecule? If we have a specific stereoisomer?The field of organic structure determination attempts to answer these METHODS OF STRUCTURE Magnetic Resonance (NMR) Excitation of the nucleus of atoms through radiofrequency irradiation. Provides extensive information about molecular structure and atom SPECTROSCOPY (IR) Triggering molecular vibrations through irradiation with INFRARED light.

Transmission over fiber is limited by the attenuation and dispersion. Multimode fibers may experience Multimode dispersion: The delayed rays cause pulse spreading Chromatic dispersion: Individual wavelengths may travel at different speeds. Dispersion creates an inherent operational limit defined as EE4367 Telecom.

Infrared Spectroscopy and Mass Spectrometry Introduction It is fundamental for an organic chemist to be able to identify, or characterize, the new compound that he/she has just made. Sometimes this can be achieved by a chemical means, such as determining the elemental composition and molecular weight.
