Replication Data for: Enhanced Resolution in EPR Spectroscopy Using para-Hydrogen Matrices
Listed in TUDOdata
PROJECT DESCRIPTION: We developed a matrix isolation experiment utilizing a closed-cycle helium cryostat, which operates at 2.5 K and enables electron paramagnetic resonance (EPR) measurements in solid para-hydrogen (p-H2) matrices.
Description
The EPR spectra of the persistent 2,2,6,6-tetramethylpiperidinyloxyl (TEMPO) radical and an in-situ generated P-centered mono-radical were recorded at 2.5 K in p-H2. The spectrum of TEMPO in p-H2 shows a narrower linewidth compared to argon, and its matrix-isolated spectrum and simulation are reported.
The P-centered mono-radical was generated in p-H2 via in-situ photolysis of the corresponding phosphorus iodide, which affords a higher spectral resolution and intensity compared to argon, neon and deuterium matrices. DATASET DESCRIPTION This dataset contains experimental data of EPR spectra and simulations of the spectra published in the manuscript "Enhanced Resolution in EPR Spectroscopy Using para-Hydrogen Matrices".

Spectra labeled as 'Figure...' are presented in the appropriate figures in the main text or the Supporting Information (SI). All captions follow the structure: Figure → compound name_number→ Matrix → (process). The magnetic field in the EPR spectra is given in mT.
The distances provided in the drawing of the setup are in mm.
