摘要：

The temperature dependence of the ionization constant of trimethylamine and trimethylamine-d9 have been determined in water at 5° intervals over the temperature range 0-45° by a conductance method. The total isotope effect is shown to be due to δIΔH - a result consistent with a simple zero point energy explanation. The temperature coefficient of the heat capacity of ionization was shown to be small and positive.
