AbstractAbstract
[en] The importance of the rate constant of the molecular fragmentation processes in mass spectrometry is estimated. The change of the rate constant with the internal energy of the ions and its importance in the isotopic effects appearing in the course of the fragmentation and in the calculation of mass spectra are discussed.

AbstractAbstract
[en] The utility of the mass spectrometry, especially of the double focusing mass-spectrometry, in the study of the unimolecular and collision-induced fragmentations is related. The energetic aspects of the upper processes, appearing from the mass spectrometric and spectroscopic measurements on the diatomic and poliatomic ions are described. (author)

AbstractAbstract
[en] Using the matrix method the basis parameters of a double focusing mass spectrometer are calculated. The calculus is performed in the second order approximation. The proposed double focusing mass spectrometer is composed of a toroidal electrostatic condenser and an inhomogeneous r-1 magnetic field. (author)

AbstractAbstract
[en] A double focusing mass spectrometer with an original geometry (Wien filter-electrostatic analyser) is presented. The image aberrations are corrected with the hexapoles lenses. The relationships for the second order aberrations coefficients in the radial and axial planes are calculated. (authors)
