I see the two groups of 4 peaks, but not the 2 groups of three peaks. So, I am expecting to see 2 groups of 3 peaks and 2 groups of 4 peaks. Same goes for H-group #3, which has the three hydrogens from H-group #4 so 3+1=4. When considering H-group #2, the three hydrogens from H-group #1 should be 3+1=4 peaks. Same goes for H group #4, since there are two adjacent hydrogens, so another 3 peaks. Using the n+1 rule, the H group #1 should create 2+1=3 peaks in a cluster. The 1st group has 3 equivalent hydrogens, with two adjacent non-equivalent hydrogens (group #2). The 31P MAS NMR spectra obtained are in good agreement with the. Heteroatoms that split nuclei are now properly highlighted in breakdowns from the NMR SignalSeek widget. Formula: Phosphorus Sesquisulfide P4S3 Molecular Weight The ChemDoodle Web Components. Fixed NMR SignalSeek widget bug in the peak breakdown that displayed duplicated peak labels.
My understanding of this problem is that there are four groups of equivalent hydrogens, and I numbered them 1-4. Removed duplicated ChemDoodle Document checkbox in the Windows Filetype Association window. Here is the chemical and the trace that results. Let me show the question and my understanding: I have a pretty limited understanding of NMR, but I thoroughly read the chapter leading up to this practice question and am having difficulty explaining all of the peaks that I am seeing. Recommended screen size of 320x480 pixels or greater.ġ.I am working on a straight-forward NMR graph as part of my test prep.
