   The measurements involved repeated equilibration of nitrogen with a water sample containing iodomethane. The sample was shaken vigorously at the required temperature in a constant temperature bath for 30 minutes. The equilibrated gas phase was then inject ed into a gas chromatograph. The experiments were performed at least three times at 10, 15, 20, and 25 oC. Each experiments involved about six equilibrations.
