Outline of Final Research Achievements

A microwave spectrometer has been constructed for the purpose of manipulating an isomerization reaction between enantiomers of a chiral molecule by coherent interaction with microwave radiation. The spectrometer has been designed to have long duration of coherent interaction by introducing a molecular beam technique. Experiment of manipulating the molecular population by coherent interaction has been performed using the spectrometer, in which the rotational transition of the OCS molecule with the lowest transition frequency was monitored. It has been confirmed that state mixing between the two rotational states, J = 0 and J = 1, of OCS is implemented by coherent interaction and its mixing ratio can be manipulated by changing duration of the microwave pulse.
