Looking at what different levels of concentration of DMSO would do to certain chemicals. There was different sets of chemicals used, a group with ethanol and a group with a fluorine attached to it. The group with ethanol included Dimethylamino ethanol, Amino ethanol, and Methoxyethanol. Using the proton NMR machine we were able to see what was happening at the different levels of DMSO. The levels of DMSO that were added were 0 for the control, then in increasingly order of 10,20,50,100,200,and 500 μL. DMSO was used because we already have known spectra of what it looks like.The peak of most interest in the proton NMR was the -OH peak. As levels of DMSO was increased, the OH peak tended to move towards the left in most cases. After seeing what the DMSO did to the ethanol chemicals, Fluorine chemicals were then looked at. The most important fluorine chemical used was 2-fluoroethanol. Having an fluorine atom in the ortho position of  2-fluoroethanol, the plan was to see if DMSO was able to detach the Fluorine. Once all these were analyzed with the proton NMR, the F19 NMR was used to establish more differences between the chemicals.

How does varying levels of DMSO change the -OH peak in ethanol containing chemicals?
