A low resolution (0.5 cm(-1)) Fourier transform infrared (FTIR) spectrum of (C2D4)-C-13 in the 2000-4800 cm(-1) region was recorded to re-analyze the two fundamental bands (nu(5) and nu(11)) and to identify the combination bands in this region. The combination bands nu(2) +nu(12), nu(6) +nu(11), nu(6) +nu(9), nu(1 )+ nu(12), nu(5) + nu(12), nu(2) + nu(11), nu(2) + nu(9), nu(5) + nu(11) and nu(5) + nu(9) were identified and their band centers (with an uncertainty off 0.1 cm(-1)) and band types were determined. In addition, the high-resolution FTIR spectrum of the fundamental nu(11 )band (2120-2250 cm(-1)) was recorded at an unapodized resolution of 0.0019 cm(-1) and its infrared (IR) lines were analyzed. Rovibrational constants up to five quartic terms and band center of 2193.75943(22) cm(-1) were derived with improved precision for the nu(11) = 1 state, with an rms deviation of 0.0019 cm(-1). Three rotational constants and the band center of the nu(2) = nu(7) = 1 state together with the b-Coriolis resonance parameter were derived with improved precision from the study of the Coriolis interactions between the two states (nu(11) = 1 and nu(2) = nu(7) = 1). Also in this work, the FTIR spectrum of the nu(5) band of (C2D4)-C-13 was measured between 2230 and 2450 cm(-1) at an unapodized resolution of 0.0019 cm(-1). For the first time, 2069 perturbed and unperturbed IR transitions of the nu(9) band, centered at 2324.358484(46) cm(-1), were fitted to obtain the a-Coriolis resonance parameter from its interaction with the nu(4) =nu(10) = nu(12) = 1 state. The IR lines of the nu(4) + nu(10) + nu(12) band were too weak for detection. Two rotational constants (A and B), the band center of the nu(4) + nu(50) + nu(12) band and the a-type Coriolis resonance parameter were derived for the first time in this work. All the rotational constants A, B and C for the nu(11), nu(9) and nu(2) + nu(7 )bands are in close agreement with theoretically calculated values using the cc-pVQZ basis set at MP2 and B3LYP levels of theory. Ground state rovibrational constants of (C2D4)-C-13 up to three sextic terms were also derived from a fit of 3153 ground state combination differences (GSCDs) with an rms deviation of 0.00037 cm(-1) from the IR transitions of the present analyses.
