Store description excerpt
The app shows a list of isotopes with non-zero nuclear spin angular momentum. Select an isotope to view its NMR properties and calculate fundamental NMR parameters. Information section For a chosen isotope, this section displays the atomic symbol with mass number, nuclear spin angular momentum, gyromagnetic ratio, and natural abundance. Calculator section Update any one parameter in a subsection to recalculate the others. - Larmor frequencies: External magnetic field and the corresponding Larmor frequencies for the chosen isotope, the proton, and the free electron. - Time domain: Number of data points, acquisition duration, and dwell time. - Frequency domain: Number of data points, spectral width, and frequency resolution. - Pulse 1: Pulse duration, flip angle, and RF amplitude in Hz and μT. - Pulse 2: Pulse duration, flip angle, RF amplitude in Hz, and RF power relative to Pulse 1. - Ernst angle: Ernst angle and repetition time for a given T₁ relaxation time. NMR Assistant An on-device AI assistant scoped to NMR topics, available where Apple Intelligence is supported. Ask questions in plain language — the assistant answers using the same calculation engine that powers the calculator, so results are always physically consistent.
