Abstract: | The kinetics of hydrogen bond dissociation and formation in solution has been studied by a lineshape analysis of the1H NMR signals of the proton donor (CF3COOH) and proton acceptor (DMF) between –100 and –170°C. It has been found that proton exchange is much slower than molecular exchange and it does not affect the lineshape. A stepwise mechanism has been confirmed.
