Laboratory submillimeter-wave detection of D2H+: a new probe into multiple deuteration.

HIRAO T. and AMANO T.

Abstract (from CDS):

A pure rotational transition (JKaKc=110-101) of D2H+ is measured in the laboratory with a high-sensitivity submillimeter-wave spectrometer. The D2H+ ions are generated in an extended negative glow discharge in a mixture of H2and D2with Ar as buffer gas (H2/D2/Ar=4/2/17 mTorr) near liquid nitrogen temperature (77 K). The transition frequency is determined to be 691.660440(19) GHz with 1 σ in parentheses. This accurately measured transition frequency should be of great use for astronomical identification of this ion.
