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.
A lot of those academic “printed on demand” books are like this, too. Very annoying. Yea they’re out of print and old library physical copies cost over $100, but the “new” ones always look like this but faded instead of over saturated.
Apparently computers are way better at deciphering this kind of text than we are because of all the training we gave them on those captchas that were just words from poorly scanned documents (they didn't know the answers to both the prompts they gave us, only one, so if we correctly typed the word that they already knew they could assume we typed the second one correctly too). All that time I was just trying to get into my Foopets account, I had no idea.
