Outline of Final Research Achievements |
To study interactions in electronic excited states of polyatomic molecules, we need to measure precisely minute effects such as line shift, broadening, or splitting. It is necessary for such precision measurement systems to have characteristics such as high spectral resolution better than 1 MHz, intense cw radiation with the power of more than several hundreds of mW, and broad wavelength range. We construct two types of such high resolution spectroscopic systems, and applied it to high resolution spectroscopies of molecular iodine and naphthalene.
