FAQ
What can NMR Calculator calculate for isotopes?
NMR Calculator can determine the nuclear spin, gyromagnetic ratio, and natural abundance for selected isotopes. It also calculates the Larmor frequency for a chosen isotope at a specified external magnetic field.
How does NMR Calculator help with signal acquisition?
For signal acquisition, NMR Calculator can compute the number of data points, duration, or dwell time when two of these are provided. It also assists in calculating spectral width and frequency resolution for NMR spectra.
What RF pulse parameters can NMR Calculator handle?
NMR Calculator can calculate pulse duration, flip angle, or RF amplitude when two of these are known. It also determines the difference in power levels between two RF pulses in dB and calculates repetition time, relaxation time, or the Ernst angle.
Can NMR Calculator determine solution concentrations?
Yes, NMR Calculator can calculate the concentration of a sample solution when the molecular weight and masses of the solute and solvent water are provided. It can also calculate the amount of solute when the concentration is given.
What devices is NMR Calculator available on?
NMR Calculator is available on iPhone, iPad, iPod, and Mac devices. It is also supported on Apple Watch.
When was NMR Calculator last updated?
The latest version of NMR Calculator, 1.3.2, was last updated on February 10, 2020.
What is the age rating for NMR Calculator?
NMR Calculator has an age rating of 4+, making it suitable for a wide range of users.
Where does NMR Calculator get its data from?
The data source for NMR-enabled isotopes and formulas used in NMR Calculator is presented within the app's 'Info' section.
