High accurate ro-vibrational spectra of 12CD4 were measured in the pentad region with a Bruker IFS125 HR Fourier transform infrared (IR) spectrometer at an optical resolution of 0.003 cm−1 and different pressures and optical path-lengths. The analysis of 1264 experimental absolute transition strengths belonging to all nine ro-vibrational sub-bands of the 12CD4 pentad was performed using the Voigt profile to simulate the measured line shape and to determine experimental line intensities. A set of 10 parameters was obtained from the weighted fit analysis of experimental data in the frame of the model of an effective dipole moment operator of the 12CD4 pentad. The obtained set of 10 effective dipole moment parameters reproduces the initial 1264 absolute transition strengths with the drms=4.52%. A line list of the studied experimental ro-vibrational transitions up to J≤25 is presented in the Supplementary data to this paper
