Definitions for "Infrared spectroscopy"
IR spectroscopy. A technique for determining the structure (and sometimes concentration) of molecules by observing how infrared radiation is absorbed by a sample.
a spectroscopic method useful in investigating the bonding in molecules.
Infrared absorption curves are used to identify the chemical functionality of waxes. Petroleum waxes with only hydrocarbon functionality show slight differences based on crystallinity, while vegetable and insect waxes contain hydrocarbons, carboxylic acids, alcohols and esters. The IR curves are typically used in combination with other analytical methods such as DSC or GS/GPC to characterize waxes.
