Abstract

The 1₁₀←1₁₁ transition of H₂D⁺ was detected in a dc discharge in Ar–H₂–D₂ mixtures with liquid nitrogen cooling and an applied axial magnetic field. The transition frequency was determined to be 372 421.380±0.100 MHz. This transition is expected to be the most favorable one for radioastronomical detection of this very crucial ion in the interstellar medium.
