Radiation damping effects on doublets. 500 MHz proton NMR spectra of the isopropyl methyl ¹H doublet in a 80% v/v solution of isopropyl alcohol in CDCl₃ as a function of the probe detuning as defined by β β = tan⁻¹(Q_cδ(δ + 2)/(δ + 1)), below Eq. (8)). Experimental (left) and simulated spectra (right) show results from perfect tuning (β = 0) and detuned in either negative (β = +52°) or negative offset (β = −43°) (Eq. (8)).
