In the latter half of the 19th century, forensic chemists began using spectroscopy to analyze substances found at crime scenes. This statement is false (f).
Rather than in the 19th century, forensic chemists started using spectroscopy in the 20th century to examine materials discovered at crime scenes. The development of a spectrometer in the 1930s allowed for the measurement of the infrared (IR) light signal. The introduction of "organic mass spectrometry" in the 1950s, which provided additional direction for equipment users, was made possible by John H. Beynon and Fred W. McLafferty.
Then, beginning in 1959, Klaus Biemann and Carl Djerassi's research groups contributed to expanding the capabilities of mass spectrometers so they could be used to analyze natural compounds and plant extracts such as cannabis, alkaloids, and cocaine.
In 1977, the Environmental Protection Agency, or EPA, allowed the use of spectrometry data as evidence in a case involving the discovery of a pesticide in animal tissues. In a criminal homicide case the next year, a court decided to accept the results of a mass spectrometry test as evidence.
