Relation between the optical detection of NMR signals by the Faraday and Cotton-Mouton effects in fluids and nuclear spin-spin coupling tensors is theoretically explored. An expression is derived for nuclear-spin--induced optical Cotton-Mouton (NSIOC-M) effect from molecules with the prepolarized nuclear magnetic moments. That contains two parts. The temperature independent part is related to hypermagnetizability due to the nuclear magnetic moments. The temperature dependent part is proportional to product between nuclear spin-spin coupling tensors and anisotropy of molecular polarizabilities. NSIOC-M effect can give information on molecular structures influids, such as bond lengths and angles. Order of magnitude of the new effect are estimated.
