Week #5 Progress

This week I used another method to acquire more chemical information of our samples. The method is called Infrared Spectroscopy (IR). It records the vibration modes of chemical bonds in the examined chemicals. By interpreting the IR spectrum for the sample, we are able to determine the kinds of functional groups exist in our sample. Moreover, by tracking the changes in IR spectra of one sample over a certain timescale, chemists are able to monitor the changes in chemical composition of the sample and speculate about the probable chemical reactions happened during the span of time.
