Spectral analysis of H-1 NMR spectra of molecules dissolved in liquid crystalline phases to obtain spectral parameters (chemical shifts, J(ij) indirect and D(ij) direct couplings) is usually a difficult and time-consuming task due to the peculiar characteristic of this kind of spectra. A procedure that links together a simulation/iteration program with graphic routines has been developed to be run on a Vax cluster. The procedure has proved to be very useful for the analysis of spectra due to molecules containing up to 11 interacting nuclei, needing reasonably low CPU times for the simulation/iteration step and providing an interactive, friendly graphic environment for such tasks as spectrum display and line assignment, whose importance increases quickly with the number of interacting nuclei.

Abstract
Spectral analysis of H-1 NMR spectra of molecules dissolved in liquid crystalline phases to obtain spectral parameters (chemical shifts, J(ij) indirect and D(ij) direct couplings) is usually a difficult and time-consuming task due to the peculiar characteristic of this kind of spectra. A procedure that links together a simulation/iteration program with graphic routines has been developed to be run on a Vax cluster. The procedure has proved to be very useful for the analysis of spectra due to molecules containing up to 11 interacting nuclei, needing reasonably low CPU times for the simulation/iteration step and providing an interactive, friendly graphic environment for such tasks as spectrum display and line assignment, whose importance increases quickly with the number of interacting nuclei.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
