Abstract: The essential oils of eucalyptus, tea tree, oregano, and lavender, and garlic, were tested on the PerkinElmer FTIR. They were tested to look at the functional groups of the essential oils and compare them to antibiotics. It was found that the essential oils did not have similar functional groups to antibiotics.

Results and Discussion:
Infrared spectroscopy (IR) was used in this experiment in order to discover the functional groups and structure of the essential oils being used in the salve. This was done by following IR procedure for each oil: tea tree, oregano, garlic, eucalyptus and lavender. A scan of the air was also performed in order to ensure that it would not interfere with the scans of each oil.
The oils that were initially tested came from the original bottle, with the exception of garlic, which was ground and then used in the IR. This yielded poor scans that were high in percentage of alcohol. Since each oil was high in alcohol, they dried quickly on the crystal of the IR. To solve this problem, each of the oils was purified and a second IR scan was run on each. The second scan showed a higher range of transmittance in each oil and a clearer scan.
Garlic also yielded a poor scan. The garlic oil being used was fresh from the plant itself, so it was high in water content. This yielded scans that looked remarkably close to scans of water, with some regions identifying the structure and functional groups of garlic oil. The IR scan showed that no components of garlic oil were close to those of antibiotics, so a second scan was not run.
Conclusion:
IR scans of antibiotics show distinct components such as clear benzene ring structures and amine functional groups. Presence of these components in a scan signify that the substance being tested in an antibiotic.
The IR scans of the oils tested in this lab only somewhat showed a presence of a benzene ring in both the original oils and the purified oils. In addition, each scan of oil showed many other components and functional groups that in no way indicated that they were antibiotic or even had antibiotic properties. It can be concluded that tea tree oil, garlic oil, eucalyptus oil, oregano oil, and lavender oil are not antibiotics. However, they still kill bacteria as proved in the lawn streak lab.
