Nuclear spin conversion in CH \(\)F induced by an alternating electric field

The nuclear spin conversion in CH3F molecules subjected to an alternating electric field was investigated experimentally. The conversion rate was found to be almost unaffected by low electric fields (\(\) V/cm) but sharply increased tenfold when the electric field amplitude exceeds the values (\(\) V/cm) sufficiently high to produce crossings of the ortho and para states of the molecule. A theoretical model for the molecular conversion in alternating electric field was developed. The results of the experiment were found to be in a good agreement with the theory.
