The nuclear spin conversion of ${\mathrm{CH}}_{3}\mathrm{F}$ molecules induced by the intramolecular spin-rotation interactions is calculated and shown to be the leading process in ${}^{12}{\mathrm{CH}}_{3}\mathrm{F}.$ For ${}^{13}{\mathrm{CH}}_{3}\mathrm{F}$ molecules, it complements the spin conversion induced by spin-spin interactions. Comparison with experimental data allows a qualitative estimate of a few relaxation rates and of the transverse anisotropy of the spin-rotation tensor that cannot be obtained with usual spectroscopic methods.
