Polarization Dependence of Excess Loss of Amorphous Coating Supermirror in Optical Region for Cavity Ringdown Spectroscopy
Mitsunori Araki, Kohsuke Suma
A long optical path length is critical in achieving sensitive spectroscopy. For cavity ringdown spectroscopy, a cavity consisting of two supermirrors provides a long path length, w…
Millimeter and submillimeter spectroscopy of the deuterated molecular ion SD+
Mitsunori Araki, Valerio Lattanzi, Christian P. Endres +1
Seven rotational and fine-structure transitions of the deuterated molecular ion SD+ in the X 3S- ground electronic state have been measured in the 271-863 GHz region in the laborat…
Laboratory Optical Spectroscopy of Vibronic Transitions of the Thiophenoxy Radical
Haruka T. Sato, Mitsunori Araki, Takahiro Oyama +1
The thiophenoxy radical (C6H5S) is a species of possible astrophysical interest due to an electronic transition in a 5000 A region. The B <-- X electronic transition of this radica…
Observations and Analysis of Absorption Lines including J = K Rotational Levels of CH3CN: The Envelope of Sagittarius B2(M)
Mitsunori Araki, Shuro Takano, Nobuhiko Kuze +5
Molecules in diffuse and translucent clouds experience cooling as a result of radiation and less excitation from collisions. However, a rotation around a molecular axis of acetonit…
Precise observations of the 12C/13C ratios of HC3N in the low-mass star-forming region L1527
Mitsunori Araki, Shuro Takano, Nami Sakai +4
Using the Green Bank 100 m telescope and the Nobeyama 45 m telescope, we have observed the rotational emission lines of the three 13C isotopic species of HC3N in the 3 and 7 mm ban…
Laboratory Optical Spectroscopy of Thiophenoxy Radical and Its Profile Simulation as a Diffuse Interstellar Band Based on Rotational Distribution by Radiation and Collisions
Mitsunori Araki, Kei Niwayama, Koichi Tsukiyama
The gas-phase optical absorption spectrum of a thiophenoxy radical (C6H5S), a diffuse interstellar band (DIB) candidate molecule, was observed in the discharge of thiophenol using…
Radio Search for H2CCC toward HD 183143 as a Candidate for a Diffuse Interstellar Band Carrier
Mitsunori Araki, Shuro Takano, Hiromichi Yamabe +2
To clarify the authenticity of a recently proposed identification of H2CCC (linear-C3H2) as a diffuse interstellar band carrier, we searched for the rotational transition of H2CCC…
A Search for Interstellar Carbon Chain Alcohol HC4OH in Star-Forming Region L1527 and Dark Cloud TMC-1
Mitsunori Araki, Shuro Takano, Hiromichi Yamabe +6
We report a sensitive search for the rotational transitions of the carbon chain alcohol HC4OH in the frequency range of 21.2-46.7 GHz in the star-forming region L1527 and the dark…
A spectral survey of the Star Forming Core of the Orion Nebula from 455 -- 507 GHz
Glenn J. White, M. Araki, J. S. Greaves +2
The results of a submillimetre wavelength spectral line survey between 455.1 -- 507.4 GHz of the Orion-KL hot cloud core are reported. A total of 254 lines were detected to a main…
Laboratory Measurement of the Pure Rotational Transitions of the HCNH+ and its Isotopic Species
M. Araki, H. Ozeki, S. Saito
The pure rotational transitions of the protonated hydrogen cyanide ion, HCNH+, and its isotopic species, HCND+ and DCND+, were measured in the 107 - 482 GHz region with a source mo…
