• Optical detection of NMR
• Antisymmetric polarizability
• Faraday effect
• Hyperfine interaction

Based on the thought on the antisymmetric polarizability induced by nuclear magnetic moments and theory of the Faraday effect, an analytical theoretical expression is derived for the nuclear-spin-induced optical rotation (NSOR) of diamagnetic saturated molecules in a circular cylinder. That consists of two parts, phi((I)) and phi((B)), induced by the intramolecular and intermolecular hyperfine interaction, respectively. By using them and the Verdet constants, NSOR for (1)H in water, hexane, cyclohexane and methyl-alcohol in liquid and H(2) gas have been calculated. The calculated NSOR for water agrees with the experiment and for three hydrocarbons predicts the same order of magnitude as water. For the samples studied except H(2) gas, phi((I)) and phi((B)) are comparable in magnitude.
