The 13C NMR spectrum of fluoroethanoic acid shows a multiplet centred at δ = 79. When the same spectrum is recorded using proton decoupling, the multiplet collapses to a doublet with a splitting of 160 Hz.

In the chemical literature, NMR data is not presented as the entire spectra because that would take up too much space during publication, instead the data is condensed as follows: 1 H NMR: chemical shifts (peaks) are reported in ppm downfield from the internal tetramethylsilane standard followed by their multiplicity (s = singlet, d = doublet, t = triplet, m = multiplet) and integrated intensity reported in parentheses. 13 C NMR: chemical shifts are reported in ppm downfield from the internal tetramethylsilane standard followed by their DEPT data reported in parentheses. MS: the m/z values for the peaks observed are reported followed by the relative intensity of the peaks in parentheses Using the following NMR and MS data to determine the structure of the organic molecule which has a molecular formula C 10 H 14 and produces this spectral data: 1 H NMR (CDCl 3 ): δ 7.1 (m, 5H), 2.5 (m, 1H), 1.6 (m, 2H), 1.22 (d, 3H), 0.81 (t, 3H) 13 C NMR (CDCl 3 ): δ 148.4 (C), 129.3 (CH), 127.9 (CH),…
