Diacetone alcohol, spectrum

Basically there are three quantities that can be measured in a high resolution NMR spectrum (1) frequencies of the resonance lines, (2) their areas, and (3) widths or shapes of the lines. Figure 1.3 shows the spectrum of a simple compound, diacetone alcohol. This spectrum arises only from the resonance of the hydrogen nuclei ( H, or protons) in the molecule, because (as we see in Chapter 2) we are able to set conditions to obtain a spectrum from only one type of... 

Figure 12 In situ C CP/MAS spectra showing reactions of natural abundance diacetone alcohol on zeolite HZSM-5. Each spectrum was the result of 20,000 scans taken at 298 K following 30 minutes of heating in the MAS probe at progressively higher temperatures.

N.m.r. spectrum of diacetone alcohol, (CH3)2C(OH)CH2COCH3 at 60 Mcps relative to TMS 0.00 ppm. The stepped line is the integrated spectrum. 

By looking at the nmr spectrum of diacetone alcohol, we can see that the chemical shifts of the four signals are 3.85, 2.6, 2.15 and 1.2.By using the relative amounts of deshielding of each type of proton, we can assign the...
