- (b) 13C NMR Select the correct answer choices to determine the NMR spectra. This molecule is and as a result would have a total of signals. The carbons labeled as expected to have a higher chemical shift (i.e. be more downfield) than 1 and 8. The respective peaks are Signals would be likely to be the shortest since they ✓hydrogen atoms attached to them. are in height.arrow_forwardWhat is the area under the NMR signal proportional to?arrow_forwardIn details explain peaks would you expect to find for t-butyl amine vs. diethyl amine vs. n-butyl amine in the Infrared spectrum?arrow_forward
