The 13C-NMR spectra is a powerful tool, useful for modeling biological activity.NMR spectra reflect quantum mechanical properties which, depends on local electrostatics and geometry of the target molecule. 13c-NMR spectrum of a compound contains a pattern of frequencies that correspond directly to the quantum mechanical properties of the carbon nuclear magnetic field.the NMR chemical shift-tensor is composed of a diamagnetic term and paramagnetic term.the diamagnetic term is directly related to electrostatic potential of nucleus, whereas paramagnetic term is dependent on orbital configuration of 13C NMR spectra, and difference between the diamagnetic and paramagnetic terms can be very large, which results in a large spectral range, this permits the use of advantageous large 13CNMR spectral diversity to build the QSDARs models, therefore we examine a large and diverse set of organic compound having biological act ivies so as to propose a fruitful models. these models combine structural information with assigned simulated 13C-NMR chemical shifts.Earlier Khadikar and Jurs have indicated that 13CNMR chemical shift is a molecular properties and thus using molecular descriptor

This book covers the recent NMR studies with the application of gaseous molecules. Among the comprehensively discussed aspects of the area it includes in particular: new multinuclear experiments that deliver spectral parameters of isolated molecules and provide the most accurate values of nuclear magnetic shielding, isotropic spin–spin coupling and relaxation times; advanced, precise and correct theoretical descriptions of spectral parameters of molecules as well as the application of gas-phase NMR measurements to chemical analysis and medicine. The progress of research in these fields is enormous and has rapidly changed our knowledge and understanding of molecular parameters in NMR spectroscopy. For example, accurate studies of the shielding for isolated molecules allow the exact determination of nuclear magnetic dipole moments, the calculated values of spectral parameters can be verified by precise gas-phase NMR measurements, and the application of hyperpolarized noble gases provides excellent MRI pictures of lungs. Aimed at graduates and researchers in spectroscopy, analytical chemistry and those researching the applications of NMR in medicine, this book presents the connections between sophisticated experiments, the theory of magnetic parameters and the exploration of new methods in practice.
