| Outline of Final Research Achievements |
Rotational transition frequencies of molecules and molecular ions were measured precisely with an accuracy of several tens of kHz by using far-infrared spectrometer in Toyama University. Measured species were D2H+, 15NH3 and HCO+ (including its isotopomers). Obtained spectral data supports the far-infrared investigations in several international research projects of interstellar species (such as ALMA, SOFIA). Our data of D2H+ successfully contributed to improve molecular parameters of this species.
