Paper Abstract

In this paper the role of hyperfine interactions in molecular ortho-para conversion is considered. The main experimental results in the CH3F spin conversion are briefly described. The general theory of nuclear spin conversion in molecules based on intramolecular ortho-para state mixing is given. Two types of ortho-para state mixing are taken into account: the spin-spin interaction between molecular nuclei and the spin-rotation interaction. The level-crossing spectra for the spin conversion in 13CH3F and 12CH3F molecules are calculated for an electric field range of 0 - 104 V/cm. The spin conversion spectrum, discussed here, is an example of a new type of Doppler-free spectroscopy.
