Molecular spectroscopy is
a method to study the molecular structure of gases, liquids and solids.
It is based on the fact that vibration and rotation of the atoms
inside a molecule has discreet energy levels. If light passes through the material
in the exact frequency – it will be absorbed.
Using a light source, an
optical apparatus, an interferometer and an optical fiber we are able to
measure the absorbance and transmittance of infra-red light in the substance.
From that we will deduce the inter-molecular structure and properties of
(also called FTIR – Fourier Transform Infra Red spectroscopy) is used in
many fields today: Medicine – to detect Cancer, Pollution control and
detection of poisons in real time, for the food industry research in many fields
and for chemistry - process control and molecular analysis.
