Promising systems for that are the fluorohalogenomethanes and
the most accurate experiments so far, at the 10−13 level for the relative transition frequency difference between enantiomers, have been performed on molecules from this class.


The observed spectral width of individual hyperfine transitions in the fully resolved spectrum is about 1 kHz, and the standard deviation of the best fit is 62 Hz.
