A chemist observes a doublet with a coupling constant (J) value of 6.6 Hz and a chemical shift (δ) about 3.00 ppm in the NMR spectrum of a compound measured using a 60.0-MHz spectrometer.
(i) If the spectrum is taken using a 300-MHz spectrometer, what would the chemical shift (δ) be?
(ii) What would the splitting value J be if the spectrum is taken using a 300-MHz spectrometer?
(iii) How many Hz from the TMS peak is this signal in the 60.0-MHz spectrum? In the 300-MHz spectrum?
