Practical aspects and trends in analytical organic-mass spectrometry,laboratory containing synthetic, separating, and spectrometric stages. Synthesis is performed in the ion source, especially in the chemical ionization chamber, and in collision gas cells. Crude ion mixtures of very different origins can be separated directly by a mass spectrometric analyzer system.

Fourier transform nuclear magnetic resonance, these systems and Fourier transforms. Next, we discuss the principles of nuclear magnetic resonance. Starting from the general properties of physical systems showing resonance phenomena and from the special properties of nuclear spin systems, the main part of this paper reviews pulse and Fourier me
