Two corrections: Braker -> Bruker (one of the only NMR vendors still around today), δrms -> δTMS (TMS = tetramethylsilane, a common reference for proton chemical shifts)

Edit: I suspect that 1L coupling constants is actually 1J coupling constants despite the proximity of the superscript to the stem; 1J referring to the coupling frequency of a 13C nucleus with a proton 1 bond away. I am wincing at the lack of 13C{1H} decoupling lol I bet the spectra are even less legible in their original form than this text is in the current form.
