The chemical shift of Ha in the molecule below was recorded at 3.85 ppm downfield from TMS on a 500 MHz spectrometer. What is this chemical shift, in Hz, on a 250 MHz NMR? Other hydrogen’s are omitted for clarity. ppm = (chemical shift in Hz)/(spectrometer frequency in MHz)
Homework Answers
relative chemical shift (ppm) = (absolute chemical shift in Hz)/(spectrometer frequency in MHz)
chemical shift, in Hz when recorded at 250 MHz
absolute chemical shift in Hz = 3.85 * 250 = 962.5 Hz
