ABSTRACT

Molecular spectra result from the periodic motions (or vibrational modes) of atomic nuclei within their respective molecules. These nuclei move together or apart along a straight-line vector; and they rotate, they vibrate, they wag, and they bend relative to their centers of gravity. The vibration and bending of molecules exhibit vibrational spectroscopic activity that may be measured using any number of spectroscopic techniques, including the nearinfrared, mid-infrared, far-infrared (terahertz), and Raman spectroscopy. The resultant spectra from these molecular vibrational measurement techniques are highly structured and complex. The process of understanding or characterizing this complexity into the spectra-structure correlations for near-infrared spectra is the purpose of this book.
