Abstract: | Recently, the nuclear‐spin‐induced optical rotation (NSOR) and circular dichroism (NSCD) for liquids were discovered and extensively studied and developed. However, so far, nuclear‐spin‐induced magnetic circular dichroism in the IR region (IR‐NSCD) has not been explored, even though all polyatomic molecules exhibit extensive IR spectra. Herein, IR‐NSCD is proposed and discussed theoretically. The results indicate that in favorable conditions the IR‐NSCD angle may be much larger than the NSOR angle in the UV/Vis region due to a vibrational resonance effect and can be measurable by using the NSOR experiment scheme. IR‐NSCD can automatically combine and give NMR spectra and IRCD spectra of the nuclear spin prepolarized samples in liquids, which, in principle, could be developed to become a unique, novel analytical tool. |
