Articles you may be interested inMagnetic circular dichroism of symmetry and spin forbidden transitions of high-spin metal ions J. Chem. Phys. 113, 5003 (2000) Recent years have witnessed a growing interest in magneto-optic spectroscopy techniques that use nuclear magnetization as the source of the magnetic field. Here we present a formulation of magnetic circular dichroism (CD) due to magnetically polarized nuclei, nuclear spin-induced CD (NSCD), in molecules. The NSCD ellipticity and nuclear spin-induced optical rotation (NSOR) angle correspond to the real and imaginary parts, respectively, of (complex) quadratic response functions involving the dynamic second-order interaction of the electron system with the linearly polarized light beam, as well as the static magnetic hyperfine interaction. Using the complex polarization propagator framework, NSCD and NSOR signals are obtained at frequencies in the vicinity of optical excitations. Hartree-Fock and density-functional theory calculations on relatively small model systems, ethene, benzene, and 1,4-benzoquinone, demonstrate the feasibility of the method for obtaining relatively strong nuclear spin-induced ellipticity and optical rotation signals. Comparison of the proton and carbon-13 signals of ethanol reveals that these resonant phenomena facilitate chemical resolution between non-equivalent nuclei in magneto-optic spectra. © 2014 AIP Publishing LLC.

“…Like the Faraday effect (NSOR), MCD (IR-NSCD) is am agnetic field-odd effect, so the IR-NSCD y IR doubles if the light beam, after crossing the mediumo nce, is reflected back through it as econd time, ap roperty that points to am ultipass opticalc ell as as ignal enhancement route. [26] But it was provedb yt he time reversal symmetry [18] that the Cotton-Mouton effect is am agnetic field-even effect and, in contrastt ot he Faraday effect, the overall effect on light due to the Cotton-Mouton effect is zero if the light, after passing through the medium once, is reflected back through it as econd time.…”

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.
