The vapor pressure difference between 12CHF3 and 13CHF3 has been measured by means of a cryogenic distillation under total reflux at 11 temperatures between 161.2 and 204.6 °K. A second‐order extension of Cohen’s column kinetics has been tested.

A simple control and data-acquisition system for electrochemical experiments is described. The system is easily interfaced to most potentiostats; a voltage waveform is supplied and data are collected, processed and stored on disk for later use. This
