The desired selectivity was achieved using pattern pulses optimized for either a particular B₁ or Larmor frequency &nu;₀. Experimental validation was performed on a heterogeneous phantom consisting of two cavities filled with two spectroscopically distinguishable liquids, one between copper disks to mimic an electrochemical cell and one between polymer disks as a reference. This dataset contains the spectroscopic raw data to reproduce all NMR spectra in the publication. Furthermore, the 3D FEM simulations of the magnetic field B₁, the corresponding histograms, and the setup used in the simulations are provided. Additionally, all custom pulse sequences are given, which were optimized based on FEM simulations. <br> <br> Description of folder contents in tree view: <br> <ul> <li><b>NMR_Data:</b> The spectroscopic raw data is stored in .rar archives for each individual experiment.</li> <ul> <li>'B_0-sel' refers to experiments discussed in Section 3.1.
