Um programa para o cálculo automático estático e dinâmico de sistemas de tubulações
… governing movement equations are transformed on normal coordinates and the solution is performed by step-by-step integration techniques. Discret or consistent mass matrices for straight and circularly curved pipe are utilized in the analysis. A complete listing in FORTRAN language for a Burroughs …

ΦΑΣΜΑΤΟΣΚΟΠΙΑ ΔΙΕΓΕΡΜΕΝΩΝ ΗΛΕΚΤΡΟΝΙΑΚΩΝ ΚΑΤΑΣΤΑΣΕΩΝ ΤΩΝ ΠΙΚΟΛΙΝΩΝ
… PROBABLY EXCITED ΠΠ* ELECTRONIC STATE ALONG THE NORMAL COORDINATES OF THE TOTALLY SYMMETRIC VIBRATIONS 1 AND 12. FINALLY, THROUGH THE RESONANT MULTIPHOTON IONIZATION SPECTRA IN A STATIC CELL AND IN A SUPERSONIC BEAM, WE STUDIED 3S RYDBERG STATE AND WE ANALYSED ITS VIBRATIONAL STRUCTURE. THAT …

Diagrammatic many-body methods for anharmonic molecular vibrational properties
… enables the formulation of the concept of Dyson coordinates and Dyson geometries, conceived as anharmonic generalizations of the normal coordinates and equilibrium geometries of the harmonic approximation, which represent a formally exact effectively harmonic treatment of molecular and crystal …

Vibrational many-body methods for molecules and extended systems
… (VCC) methods on the basis of a QFF in normal coordinates. We have identified algebraically and eliminated several terms in the formalisms of VSCF that have nonphysical size dependence, leading to compact and strictly size-extensive equations. This size-extensive VSCF method (XVSCF) thus …

Effects of non-planar distortions in porphyrin compounds on their properties and functionality
… spectroscopy, resonance Raman spectroscopy, and normal-coordinate structural decomposition (NSD) analysis of simulated and X-ray crystal structures. Concerning the optical properties, the view that the large red shifts seen in the optical absorption bands of peripherally crowded nonplanar …
