Researches

Following three research subjects are under investigation.

Microwave spectroscopy of intersteller molecules

These molecules are under investigation. All of the molecules have internal rotations and are candidates for astronomical detection.

  • dimethyl ether ; (CH3)2O
  • methyl alcohol ; CH318OH
  • methyl mercaptan ; CD3SH
  • methyl formate ; HCOOCH3
  • ethyl methyl ether ; CH3CH2OCH3

Control of translational motion of polar molecules using microwave

 We are developing techniques for focusing, decelerating, and trapping polar molecules using an intense microwave field. A time-varying standing wave of the microwave field is enhanced in a superconducting cavity, and it can control the translational motion of polar molecules flying through the cavity. Our method is advantageous for controlling molecules in high-field seeking states, and would be useful for precision measurements for high-energy physics using cold and slow (or trapped) molecular beams.

Near-infrared spectroscopy

We are also preparing laser systems for near-infrared spectroscopy.
