As a result of analyzing the spectrum using a ¹H-NMR spectrometer and a ¹H-NMR spectrum prediction program for Visipaque contrast agent, the molecular structure positions in the 2.18 ppm and 2.17 ppm regions were found to be different from each other. The 2.25 ppm and 2.34 ppm regions did not appear in the spectrum analysis using the spectrometer, but did appear in the analysis using the prediction program. In addition, the 2.58 ppm region appeared in the spectrum analysis using the spectrometer, but did not appear in the analysis using the prediction program. The 4.42 ppm region did not appear in the spectrum analysis using the spectrometer, but did appear in the analysis using the prediction program. In addition, the 5.61 ppm region appeared in the spectrum analysis using the spectrometer, but did not appear in the analysis using the prediction program. Based on this, it is thought that if we analyze it using the prediction program as a reference, we will be able to identify the chemical structure more clearly.
