The 1H NMR spectrum of CH3OH recorded on a 500 MHz NMR spectrometer consists of two signals, one due to the CH3 protons at 1715 Hz and one due to the OH proton at 1830 Hz, both measured downeld from TMS. (a) Calculate the chemical shift of each absorption. (b) Do the CH3 protons absorb upeld or downeld from the OH proton?
