NMR spectroscopy in biology and medicine is generally performed in aqueous solutions, thus in (1)H NMR spectroscopy, the dominant signal often stems from the partly suppressed solvent and can be many orders of...

[Question from NMRWiki Q&A forum] same parameters but difference in phase why?
same parameters but difference in phase why?
hi, though this question seems to be easy for you but i am new for this software and to this field. Recently, i took silicon spectra in 500mhz(bruker) seems to be good (i.e.one silicon peak and one nmr tubes broad peak) but when i used same parameters for another sample where i got single peak as i expected but nmr tube peak is inverse this time. I just copied previous parameters only why i got such a inverse signal.If anybody know please help me.
thank you

Anal Bioanal Chem. 2004 Mar;378(6):1520-7
Authors: Macnaughtan MA, Smith AP, Goldsbrough PB, Santini RE, Raftery D
A new difference probe for nuclear magnetic resonance (NMR) spectroscopy is presented. The difference probe uses two saddle-shaped coils to excite and detect two samples simultaneously. The samples are held in a specially modified 3-mm NMR tube with an Ultem plastic disk to...

Difference between Bruker and Varian machine
Hello
I want to transplant some Varian pulse sequence to our Bruker machine. But I don't know exactly how to change the pulse phase. Some people told me I can keep all the pulse phase and just inverse the reciever phase. But I can't get the desired results by doing this. In some paper I just notice some more complicated changes to apply the same pulse sequence onto both machines.

NMR question about chemical shifts and frequency difference between two lines?
The 13C chemical shifts for the carbonyl and methyl resonances of acetone are 206.68 and29.92 ppm, respectively (referenced to TMS at 0 ppm).a) If this spectrum was run on a Varian INOVA 400 NMR spectrometer, what is the frequencydifference in Hz between the two lines? (Assume <ref = 100.0650368 MHz) (2 points)b) What is the difference in magnetic field experienced by the carbonyl carbon vs. the methylcarbons. (4 points)thank you Allision!!so then i haver a difference of 17,717 Hz.for b) now I do not have any textbooks for this course but i did go to the library and picked up 4 differnet...
