Abstract
Correction for ‘19F multiple-quantum coherence NMR spectroscopy for probing protein–ligand interactions’ by Anna Zawadzka-Kazimierczuk et al., RSC Adv., 2018, 8, 40687–40692.
In the original manuscript, Fig. 1 contained an error, for which two pulsed field gradients in the NMR pulse sequences depicted should not be present. The correct figure and caption are as follows.

| Fig. 1 Scheme of the 5Q pulse sequence for T2 measurements of the SF5 system, together with coherence transfer pathway. All pulses were selective shaped pulses. The pulses acting on one type of fluorine nuclei (F or F4 group) were sinc-shaped; their length was set to 250 μs and offset was set on the frequency of the group. The pulses applied simultaneously on F and F4 groups were cosine-modulated sinc-shaped pulses; their length was 250 μs and offset was set in the middle between the two frequencies. The Δ1 delay was set to 6.28 ms and the relaxation delay Δ was incremented. The pulse phases were set to x, unless shown explicitly. On the phase ϕ1 a 10-step phase cycle was performed to select the coherence of ±5 order during the multiple-quantum period. Additionally, on the phase ϕ2 a 4-step phase cycle was performed. | ||
