Generation of ground state HD+ based on the [2+1’] resonance-enhanced threshold photoionization (RETPI) is provided for rovibrational transition frequency measurement. Using state-selected [1+1’] resonance-enhanced multiphoton dissociation, the yield of rovibrational ground state HD+ is evaluated. The state preparation of HD+ lay an important basis of the proceed measurement which detects the (v=0,j=0)→(v=6,j=1) rovibrational transition frequency.
