Astronomical surveys of interstellar molecules, such as those that will be available with the very sensitive ALMA telescope, require preliminary laboratory investigations of the microwave and submillimeter-wave spectra of new molecular species to identify these in the interstellar media. We build a linelist that should allow us to detect HCOOCD₂H, provided it is present in the interstellar media in a suitable concentration. The experimental spectra of HCOOCD₂H have been recorded in the microwave and submillimeter-wave energy range. Line frequencies were analyzed using an internal axis method-like treatment taking into account the CD₂H internal rotation. 5933 lines of HCOOCD₂H have been assigned and their frequencies were reproduced with a unitless standard deviation of 1.6. A linelist with calculated frequencies and intensities was built and spans the 50-660GHz spectral region. The frequency accuracy is better than 0.1MHz. The pure rotation spectrum of the CD₂H-methyl formate isotopolog (HCOOCD₂H) has been observed in laboratory for the first time.
