Mid Infrared 4,500 to 400 cm-1 (2.5 to 50 μm) Far Infrared 400 to 12.5 cm-1 (50 to 800 μm) Using these units, visible light is from 0.36 to 0.75 μm, or 27,778 to 13,333 cm-1. There is a discussion of these units below. In the case of infrared spectroscopy, infrared light passes through a sample and certain

Vibrational Spectroscopy (Infrared, IR-Spect.)

Infrared Absorption For a molecule to show infrared absorptions it must possess a specific feature: an electric dipole moment which must change during the vibration. A dipole moment, µ is defined as the charge value (q) multiplied by the separation distance (d) between the positive and negative charges. µ = qd (C.m)

This was done with the help of the Wesleyan Earth and Environmental Science and Physics departments. The light source was an old slide projector; the spectrophotometer was a Pyroelectric radiometer system; and the ...

Infrared Spectroscopy

Infrared (IR) spectroscopy is one of the most common spectroscopic techniques used by organic and inorganic chemists. Simply, it is the absorption measurement of different IR frequencies by a sample positioned in the path of an IR beam. The main goal of IR spectroscopic analysis is to determine the chemical functional groups in the sample.
