5. Explain one way in which magnetic resonance images can be obtained This is the proton NMR spectrum of an organic compound that has the empirical formula CsHi204. What is it? The NMR spcctrum shows a single peak at δ 6.83 (r 3.17), a quadruplet at δ 4.27 (r 5.73), and a triplet at δ 1.32 (r 8.68). For the multiplets the coupling constant is about 7 Hz. The intcgrator readings arc in the ratio 1:2:3, rcspectively. Empirical formula is C8H12 04 . Hz 500 400 300 200 100 0 8.0 2.0 7 0 3.0 6.0 4.0 5.0 5.0 4.0 6.0 3.0 7.0 2.0 8.0 1.0 9.0 0 ppm δ 10.0 ppmã
