We performed the systematic measurements of line intensities of ro-vibrational absorption transitions of the nu(3) and 2 nu(3)-nu(3) parallel bands of (CH3Cl)-C-12-Cl-35 and (CH3Cl)-C-12-Cl-37 isotopes. The spectra were recorded in the spectral region between 650 and 800 cm(-1) with a high-resolution Fourier transform spectrometer. A mono-spectrum fitting technique was used to fit a series of seven spectra at pressures of CH3Cl ranging from 1.02 to 10.24 mbar to retrieve line intensities of 2385 transitions of the two isotopic species. The measured line intensities are discussed in relation to rotational quantum numbers, and used to derive the square of the transition dipole moments for each line. The analysis of these moments allows us to derive a consistent set of line intensity parameters, such as vibrational transition moments, band intensities as well as Herman-Wallis coefficients for both bands...
