How Much Does a Lie Detector Test Cost. How Much Does a Lie Detector Test Cost. The application potential of polygraphs makes this tool one of the most sought after private investigator services. Many people in the UK seeking the truth in a matter that is of interest to them have turned to private investigators to have polygraphs administered.
Confidence votes 228. Infrared spectroscopy, or IR spectroscopy, is a method of spectroscopy used by organic chemists to help determine the structure of an unknown molecule. An IR spectrum will have peaks based on how much light was visible when shone through different parts of the molecule.
In this type of spectroscopy, each optical wavelength that is recorded is encoded with an audio frequency containing the original wavelength information. A wavelength analyzer can then reconstruct the original spectrum.amma radiation is the energy source in this type of spectroscopy, which includes activation analysis and Mossbauer spectroscopy. Infrared Spectroscopy. The infrared absorption spectrum of a substance is sometimes called its molecular fingerprint.
