Nuclear magnetic resonance (NMR)
spectroscopy has become one of
the most powerful technologies to aid research in numerous scientific
disciplines. With the development of consumer electronics, mobile
devices have played increasingly important roles in our daily life.
However, there is currently no application available for mobile devices
able to perform basic NMR data processing. In this article, we introduce
Touch NMR, a free iPad application for basic NMR data processing.
It is capable of handling free induction decay data in the Agilent,
Bruker, and JEOL Delta formats. It can also accomplish basic NMR data
operations, such as fast Fourier transform, phase correction, baseline
correction, referencing, peak picking, integration, and others. Furthermore,
in Touch NMR, distortionless enhancement by polarization transfer
spectral editing, relaxation-time fitting, and 2D spectrum displaying
with projections in two dimensions are also available. For the purpose
of offering users a better experience, multitouch functionality and
cloud storage are additionally provided. Finally, it is believed that
Touch NMR can save considerable time for both instructors and students
in tackling NMR data processing, during in-class education as well
as during exams.
