Abstract
Correction for ‘Analysis of 1-aminoisoquinoline using the signal amplification by reversible exchange hyperpolarization technique’ by Hye Jin Jeong et al., Analyst, 2020, 145, 6478–6484. DOI: 10.1039/D0AN00967A.
The authors note that the two following statements were given incorrectly in the original article.
“As a result of polarization transfer, the H-3 proton signal was enhanced 540-fold (0.33%). Moreover, the NMR intensity of H-5, 6, 7, 8 and H-4 protons was enhanced 834- and 986-fold (0.51 and 0.61%), individually (Fig. 3).”
“Our study revealed a 2360-fold amplification of the protons of 1-AIQ following polarization transfer at the Earth's magnetic field.”
The correct expressions are as follows:
“As a result of polarization transfer, the H-3 proton signal was enhanced 0.33%. Moreover, NMR intensity of H-5, 6, 7, 8 and H-4 protons was enhanced 0.51 and 0.61%, individually (Fig. 3).”
“0.48% amplification on average of the protons of 1-AIQ following polarization transfer at the Earth's magnetic field has been reported in our study.”
The authors also note that Fig. 3 is incorrect, the correct figure and caption for Fig. 3 are given below:
