Determination of Atomic Masses by Microwave Methods

  • S. Geschwind
Part of the Encyclopedia of Physics / Handbuch der Physik book series (HDBPHYS, volume 8 / 38 / 1)

Abstract

The development of microwave techniques in the last decade has resulted in another tool for the accurate determination of atomic masses. The characteristic rotational frequencies of molecules lie in the microwave region (electromagnetic spectrum from about 1 to 300 mm in wavelength) and comprise the bulk of the microwave spectra of gases. By measuring the frequency shift which occurs in the pure rotational absorption spectrum of a molecule when another isotope is substituted for one of the atoms, accurate information about the relative masses of the isotopes can be obtained.
