🍋 ¹H NMR of Lemon Juice
Freshly squeezed science!
This proton NMR spectrum of lemon juice reveals a rich mixture of natural metabolites. The intense multiplets around 2.6–2.8 ppm are from citric acid, the dominant organic acid in lemon.

My standard speed on this QNP-equipped Bruker is 100–150 routine ¹H spectra per hour (not ideal quality, of course — Z1 + Z2). Most folks don’t believe me 🤣

Multiplet of the week 🧲 ᗑ. This particular proton has four couplings to the ¹H nuclei of two diastereotopic CH₂ groups (³J = 4.95, 5.66, 6.00, and 7.28 Hz) and a ³J coupling of 6.63 Hz to the methyl protons.

Check out this monster 👿 ddqdd. The guys from CT convinced me to try this analysis, and it works great! However, from a practical point of view, I have to say I’m satisfied with tqt. 👇🧵
