| Outline of Final Research Achievements |
In this research projects, we have developed a phase-sensitive detection system for the MW radiation induced by coherent excitations using a phase-locked laser and MW radiation as following subjects.
1) Detection of the induced Raman process in the rovibrational states of CH4 using two single mode cw-IR lasers. 2) Evaluation for the phase sensitive detection system based on a SIS mixer in 150 GHz region. 3) Measuring the mm-wave spectrum of a chiral S2Cl2 molecule using a chirped FTMW spectrometer, and determination of the rotational molecular constants. 4) The first detection of ortho-para transitions in the S2Cl2 molecule by using high-sensitive FTMW spectrometer.
