A brief sketch is given of the historical background of time as it has been applied to navigation. The very great progress in time determination and the stringent requirements for precise frequency have made it possible and necessary to use an atomic

The specific heat of ammonia is calculated in the temperature range from 0°C to 150°C. The effect of the anharmonicity of the 948 cm—1 vibration on the specific heat is very noticeable. Small corrections due to the stretching of the molecule by c
