[SPROM – Un programme performant pour les simulations RMN/IRM de cohérences quantiques multiples inter- et intra-moléculaires]
Un progiciel a été développé pour simuler les spectres et les images de résonnance magnétique nucléaire. Combinant la matrice opérateur de produit et les équations de Bloch non-linéaires, le logiciel simule efficacement les effets classiques et quantiques, notamment le couplage scalaire, le couplage dipolaire, la diffusion translationnelle, le décalage chimique, l'amortissement radiatif, la relaxation transverse et la relaxation longitudinale. Un des aspects les plus originaux de ce logiciel est sa capacité à incorporer les effets de cohérences quantiques multiples inter- et intra-moléculaire dans les systèmes complexes de spins multiples couplés, ce qui est difficile avec les progiciels existants. Doté d'une interface graphique conviviale, lee logiciel, écrit en Visual C++, est facile d'utilisation.
A software package has been designed to simulate nuclear magnetic resonance spectra and images. Combining the product operator matrix with the non-linear Bloch equations, the software can efficiently simulate classical and quantum effects including scalar coupling, dipolar coupling, translational diffusion, chemical shift, radiation damping, transverse relaxation, and longitudinal relaxation. One of the most unique features of the software is its ability to incorporate effects of inter- and intra-molecular multiple quantum coherences in complex multiple-spin coupled systems, which are difficult with other existing software packages. The software, written in Visual C++, has a friendly graphical user interface and is easy to use.
