...Molecular Biophysics 1 Problems 1.1 Q1 Two non-eqivalent protons, A and B, have chemical shift (measured with respect to the reference standard TMS) of 2.2 ppm and 7.2 ppm, respectively. By how much in Hz will their resonances be separated if the spectrum is recorded using a 500 MHz spectromete...
