DOI: 10.1002/mrc.5499
Abstract: Overcoming line broadening of labile protons and achieving high‐resolution NMR spectra is crucial for the structural and conformational analysis of organic molecules. Recently, Ma et al. (Magn. Reson. Chem. 2024, 62, 198–207) demonstrated the effectiveness… read more here.

DOI: 10.1103/physreva.103.022826
Abstract: Accurate measurements of optical line broadening and microwave hyperfine transition shifts are essential for optimizing the performance of buffer-gas atomic clocks. Previous literature has reported inconsistent measurement values. We report measurements of the ${D}_{1}$ transition… read more here.
