The NMR signal processing algorithm is described. The home-built NMR-equipment allows us to clearly register the splitting in proton spectra, for example, due to the J -interaction with such nuclei as Si or C at their natural abundance (4.7 and 1.1%, respectively)....
Re: CNMR question « Reply #11 on: May 13, 2015, 12:39:44 PM » QUESTION: Equilibrium of conformers is very fast at room temperature. Therefore, distinguish of conformers by NMR spectroscopy demands temperatures, as low as - 60oC. Then, what happens here and so, both conformers...

A lover of spectroscopy and chocolate. Re: Question about 1,10-phenanthroline's IR spectra «Reply #3 on:October 26, 2015, 09:28:19 AM » The problem is that all the carbons and nitrogens in phen are conjugated. Probably most of phen's IR spectrum is dominated by aromatic breathing...
aSince the silver clustertBu-4features a ligand to iodide ratio of 1 : 2 and since monitoring the formation of the complex via NMR spectroscopy indicated complete consumption of the imidazolium salttBu-3, the fate of the remaining starting material is unclear. 从银clustertBu-4features一ligand到...

It depends on what kind of resolution you have (which in turn is dependent on experimental factors, such as the purity of your crystal) Now in this specific case, you've got a chlorine atom (very electronegative, lots of electronic density) with a tiny hydrogen next to it, so you're ...
«Reply #2 on:February 02, 2017, 06:11:24 AM » My background is in food chemistry. During my MSc studies I had a fair training in organic spectroscopy (to be precise: NMR, IR, UV-Vis, MS). -When it comes to NMR I used it quite a bit during MSc thesis research, but my...
On-resonance spectrum- This refers to the spectrum that is recorded with selective saturation of the protein protons. The signal intensities of this spectrum is referred by the paper as I From the two spectra, a difference spectrum is determined through subtraction between the signal intensities of...
