Implications of Life
Scientific Research and Design
Infrared Spectroscopy is another important tool for organic chemical analysis and structural identification. An IR spectrum is produced by absorption of energy (4000-400 cm-1) due to vibrations of polar covalent bonds.
Positive: The IR spectrum of the unknown compound can be compared to tables of functional groups to determine structure. A structure indicative of compounds contained only in life samples would be a positive. A structure sometimes indicative of life would require further testing.
Negative: An identifiable structure characteristic of inorganic life.
False-Positive: A structure sometimes indicative of life could be a false-positive, but again, further testing would clarify.
