TAILIEUCHUNG - Infrared and Raman Characteristic Group Frequencies

Both infrared and Raman spectroscopy are extremely powerful analytical techniques for both qualitative and quantitative analysis. However, neither technique should be used in isolation, since other analytical methods may yield important complementary and/or confirmatory information regarding the sample. Even simple chemical tests and elemental analysis should not be overlooked and techniques such as chromatography, thermal analysis, nuclear magnetic resonance, atomic absorption spectroscopy, mass spectroscopy, ultraviolet and visible spectroscopy, etc., may all result in useful, corroborative, additional information being obtained | Infrared and Raman Characteristic Group Frequencies Contents List of Charts and Figures List of Tables Symbols Used Preface 1 Introduction Spurious Bands in Infrared and Raman Spectra Spurious Bands at Any Position Spurious Bands at Specific Positions Positive and Negative Spectral Interpretation Negative Spectral Interpretation Positive Spectral Interpretation Regions for Preliminary Investigation Preliminary Regions to Examine Confirmation Chemical Modification Collections of Reference Spectra Final Comment References 2 Alkane Group Residues C-H Group Alkane Functional Groups Alkane C-H Stretching Vibrations Alkane C-H Deformation Vibrations Alkane C-C Vibrations Skeletal Vibrations References 3 Alkenes Oximes Imines Amidines Azo Compounds c c C N N N Groups Alkene Functional Group C CX xi Alkene c c Stretching Vibrations 68 xiii Alkene C-H Stretching Vibrations 69 Alkene C-H Deformation Vibrations 69 xvi Alkene Skeletal Vibrations 69 Oximes C N OH.
