2. Below is the observed ESR spectrum of the butadiene anion radical. Interpret the spectrum (i.e.,...
The EPR spectrum of a cyclo-tetrasilane radical anion is shown below. a) Explain the observed coupling. (Hint: 1H: I=1/2, 99% abundant; 13C: I=1/2, 1.0% abundant; 14N: I=1. 99.9% abundant; 29Si: I=1/2, 5.0% abundant; not all the expected lines may be observed.) b) Based on your explanation of the observed coupling in part a), explain the relative intensities of the lines in this spectrum (Hint: You may need to construct a Pascal's triangle for a nucleus with I>1/2).
Hi could you help me with this problem please? The following spectroscopic data were obtained for an organic compound: i. MS (relative abundance in parentheses): M+ = 86 ; signals at 29 (92) and 41 (100) among others ii. IR (cm-1): 3100 (weak sharp), 2970 (medium sharp), 2850 (medium), 1650 (weak sharp), 1100 (strong sharp) iii. H1 NMR : Signal A at 4 ppm (3H, triplet), Signal B at 3.53 ppm (2H quartet), Signal C at 4.01...
NMR IR CAN YOU PLEASE ANSWER AS SOON AS POSSIBLE THANK YOU PLEASE EXPLAIN IT IN DETAIL THANK YOU Experimental Data Only report the IR absorptions that provide diagnosis for the major functional groups. Copies of your spectra will be included in your lab report with this information written on the spectra. However, the information should also be included in the body of the report in a text format similar to the example given below IR cm1: 1735 (C-o); MS:...
