Egg nog gives a surprisingly clean spectrum. Makes you wonder about the processing.Merry Christmas!
Hi John,I was a bit surprised by that too. I did not use any unusual processing. The sample was just plain egg nog with 2 drops of D2O added. The proton spectrum was acquired with 2 seconds of presaturation on the water. No apodization was applied prior to Fourier transformation.2 Hz of exponential line broadening was applied to the carbon data.Glenn
GlennIt appears that you are mixing your egg nog with pure ethanol.Happy holidays,Bruce
Hi Bruce,The two spectra on the bottom are indeed from fine Canadian white rum. I was a bit surprised to see that it looked like pure ethanol as well. However, since it is 40% ethanol by volume, the ethanol signals are huge in comparison to the many other compounds present in much lowwer concentrations. In this case the taste buds outperform the NMR spectrometer.Glenn
Is that the same stuff we were drinking before you decided to haul the telescope out and show me the rings of Saturn?
Dear Rumple,No, if my memory derves me well, the night we observed the rings of saturn we were enjoying amber rum. The data in the figure were collected on white rum (the type preferred by Canso residents)Merry ChristmasGlenn
