I have been pondering the assignment for the 1H NMR peaks observed. I can't really make sense of the observations from what I know. https://www.chemicalbook.com/SpectrumEN_104-93-8_1HNMR.htm
My question is the assignment of the signal between 6 and 7.5ppm. Unlike the way it is currently assigned, I would imagine Ha to be the most upshifted peak (near 7ppm) because methoxy group is slightly electron withdrawing and therefore de-shield the protons of Ha more than Hb (Hb is near methyl group which is slightly electron donating).
Any idea of how you would interpret the peak assignments?
