An automated scheme is described which locates the centers of cross peaks in two-dimensional correlation spectra, even under conditions of severe overlap. Double-quantum-filtered correlation (DQ-COSY) spectra have been investigated, but the method is also applicable to TOCSY and NOESY spectra. The s

Abstract
The twoโdimensional mass spectra (metastable mapping) of ten biogenic amines derived from the amino acid 2โphenylalanine are described. This technique permitted the identification of almost all the fragmentations of singly and doubly charged positive ions formed by electron impact and decomposing in the different parts of a reverseโgeometry mass spectrometer. The results obtained are discussed in order to establish the main fragmentation pathways common to all the amines belonging to the general class of 2โphenylethylamines and to identify the fragmentations characteristic of each amine.

A hydrodynamical approach is employed to study the collective excitations of a two-dimensional electron gas confined in a ring geometry, under a normal magnetic field. The theory predicts a rich spectrum of magnetoplasma excitations, with several branches of high- and low-frequency resonances. It is
New methods for optimum separation of (2)H MAS NMR spectra are presented. The approach is based on hypercomplex spectroscopy that is useful for sign discrimination and phase separation. A new theoretical formalism is developed for the description of hypercomplex experiments. This exploits the proper
