Atomic Masses of Nuclides,that the atoms of all elements were tightly bound combinations of hydrogen atoms. When slightly later it was discovered that some atomic weights were definitely non-integral numbers, one had either to abandon this hypothesis or to assume that atoms of one element could have different masses. The fir

Determination of Atomic Masses by Microwave Methods,istic 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 a

Determination of Nuclear Quadrupole Moments, shape and hence is an important source of information about nuclear structure. Effects due to the non-spherical distribution of charge in a nucleus were first discovered only about twenty years ago, and for the next decade nuclear quadrupole moments were detected only rather rarely and by specializ

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.

This interaction splits the energy levels of a single isotope into a number of states. Frequently combinations of both types are observed in a single spectral line.
