Molecular spectroscopy and chirality

The nuclear magnetic resonance spectra (1H and 19F) of pentafluorobenzene at ν0 = 6.14, 94.1, and 100.0 MHz have been analyzed. Subspectral analysis, perturbation theory, and direct analysis were applied to the low-frequency spectra in order to obtain all the magnitudes and relative signs of the parameters. It was demonstrated that although at high frequencies a loss of information due to weak coupling should in principle arise, it is still possible to obtain the same results by exploitation of high-precision measurements through computer iteration and by double irradiation (tickling).
