SNIP measures contextual citation impact by weighting citations based on the total number of citations in a subject field.
SJR is a prestige metric based on the idea that not all citations are the same. SJR uses a similar algorithm as the Google page rank; it provides a quantitative and a qualitative measure of the journal’s impact.
The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years.

To calculate the five year Impact Factor, citations are counted in 2014 to the previous five years and divided by the source items published in the previous five years.

The Journal of Magnetic Resonance presents original technical and scientific papers in all aspects of magnetic resonance, including nuclear magnetic resonance spectroscopy (NMR) of solids and liquids, electron spin/paramagnetic resonance (EPR), in vivo magnetic resonance imaging (MRI) and spectroscopy (MRS), nuclear quadrupole resonance (NQR) and magnetic resonance phenomena at nearly zero fields or in combination with optics. The Journal's main aims include deepening the physical principles underlying all these spectroscopies, publishing significant theoretical and experimental results leading to spectral and spatial progress in these areas, and opening new MR-based applications in chemistry, biology and medicine. The Journal also seeks descriptions of novel apparatuses, new experimental protocols, and new procedures of data analysis and interpretation - including computational and quantum-mechanical methods - capable of advancing MR spectroscopy and imaging.
With a solid track record spanning over four decades, the Journal of Magnetic Resonance is known for introducing high-quality, breakthrough articles. These have been seminal to the current state-of-the-art achieved by NMR, ESR, MRI and NQR, and it is a tradition we aim to preserve and enlarge. The Journal's readership spans the full range of disciplines impacted by magnetic resonance, including experts interested in magnetic resonance within the context of physics, engineering, materials sciences, chemistry, biophysics, structural biology, in vivo biochemistry, biology, preclinical analyses, and human imaging.
Emphasis is placed on expanding the basic principles and techniques underlying this branch of spectroscopy, as well as on state-of-the-art applications of novel MR experiments to all the research areas of interest to our constituency. Manuscripts that only make routine use of well-established techniques or minor spectroscopic contributions, are not appropriate for the Journal.
