1 Analysis of a Mixture of Xylene Isomers by FTIR Spectroscopy By: Anna Swyers Experiment preformed on February 14 th , 2018 Abstract: FTIR was used to calculate the amount of ortho, meta, and para isomers in 2 unknown solutions based off of the FTIR spectra of all 3 samples mixed in different concentrations.

2 Table of Contents: Introduction – 2 Method/Experimental – 2 Results – 3 Discussion – 8 Introduction: Infrared spectroscopy is useful in that it can quickly analyze compounds based on their functional groups and how each group vibrates. The spectral bands in IR are narrower than the UV-vis bands which means IR reduces overlap allowing for the different functional groups to be identified. Fourier-transform infrared spectroscopy (FTIR) uses a mirror rather than a grating to obtain a spectrum. Since FTIR is able to distinguish between different types of functional groups it is used in this lab to determine the concentration of ortho, meta, and para Xylene isomers.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
