In an AB spectrum the two weaker lines are found to have frequen¬cies of 40.8 Hz and 9.18 Hz, and the two stronger lines are found to have frequencies of 31.1 Hz and 18.7 Hz, measured relative to some arbitrary origin.
(a) Using the method described in section 12.7.1 on page 468, determine the Larmor frequencies of the two spins and the coupling constant between them.
(b)Use these data to compute the intensities of the lines and hence sketch the spectrum.
(c) Suppose that the static magnetic field is doubled. Compute the frequencies and intensities of the lines you would then expect to see.
