Abstract:
Milk is a fluid containing several substances, and its composition depends on several factors. Vibrational spectroscopy is a powerful tool to determine the constituent concentrations and qualitative characteristics of dairy products. Vibrational spectrometry covers a series of well-established analytical methodologies suitable to be employed for both qualitative and quantitative purposes. In the first part of this review, theoretical aspects on vibrational techniques are presented; in the second part, the most important papers, published during the period 2009-2015, related to milk analysis are discussed.

IR Spectroscopy: Molecular Vibration Overview
Stretching vibrations are vibrational motions that occur along the bond line, changing the bond length or distance between two bonded atoms. They are further distinguished as symmetric or asymmetric. In symmetric stretching, the...

However, the stretching absorptions for the C=O bond vary depending on the structure of carboxylic acids. The C=O bond of the free carboxylic acids shows a higher stretching frequency, 1760 cm−1, while H-bonded carboxylic acids (dimers) exhibit stretching absorptions at a lower frequency,...
