The computed energy spectra, expectation values and diamagnetic susceptibility X were found to be more influenced by the external magnetic field strength.

• Abstract: We investigate the nonrelativistic magnetic effect on the energy spectra, expectation values of some quantum mechanical observables and diamagnetic susceptibility for some diatomic molecules bounded by the Isotropic oscillator plus inverse quadratic potential. The energy eigenvalues and normalized wavefunctions are obtained via parametric Nikiforov-Uvarov method. The expectation values square of position r2, square of momentum p2, kinetic energy T and potential energy V are obtained by applying Hellmann-Feynman theorem and an expression for the diamagnetic susceptibility X is also derived. Using the spectroscopic data, the low rotational and low vibrational energy spectra, expectation values and diamagnetic susceptibility X for a set of diatomic molecules (I2, H2, CO, HCl) for arbitrary values Larmor frequencies are calculated. The computed energy spectra, expectation values and diamagnetic susceptibility X were found to be more influenced by the external magnetic field strength and inverse quadratic potential strength g than the vibrational frequencies and the masses of the selected molecules.

  Magnetic field effects (MFE) in certain chemical reactions have been well established in the last five decades. We employ elaborate and realistic models of radical-pairs, considering its coupling to the local spin environment and the sensor. For two model systems, we derive signals of MFE detectable even in the weak coupling regime between radical-pair and NV quantum sensor.

  Heaviside-Larmor duality symmetry of Maxwell's equations is broken by the usual form of magnetic interaction energy. Local fields should be treated as a necessity for correctly translating between the microscopic world of the dipole and the macroscopic world of the measured fields. We compute the magnetic dipole decay rate in a magneto-dielectric with local-field effects taken into account.
