NMR Spectrum
Prediction： 1H-NMR analysis in CDCl3 indicates no peak for tris(hydroxymethyl-aminomethane around 3.2 ppm. However, three additional signals at around 1.6, 1.2, and 0.8 ppm are present for a total of 11 protons indicating the sample contains a substantial amount of another organic compound
