Textbook Question

Chapter 9, Problem 50P

The 1 H NMR study of DMF (N, N-dimethylformamide) results in different spectra according to the temperature of the sample. At room temperature, two signals are observed for the protons of the two methyl groups. On the other hand, at elevated temperatures (> 130 °C a singlet is observed that integrates for six hydrogens. Explain these differences.
