    "abstract": "A complete theoretical model of the nuclear spin conversion in 13CH3F induced\nby intramolecular ortho-para state mixing is proposed. The model contains\nparameters determined from the level-crossing spectra of the 13CH3F spin\nconversion. This set of parameters includes the ortho-para decoherence rate,\nthe magnitude of the hyperfine spin-spin interaction between the molecular\nnuclei and the energy gap between the mixed ortho and para states. These\nparameters are found to be in a good agreement with their theoretical\nestimates.",
