Streszczenie:High resolution spectra of methylene chloride in natural abundance are recorded in wide spectral regions from 0.075 up to 1.090 THz. The 5095 multiplet center frequencies with the value of quantum number Jmax=107 and Kamax=20 were assigned to the 12CH235Cl2 species. A weighed fit of the experimental data allowed us to obtain a set of 20 rotational and centrifugal distortion parameters which reproduce the initial experimental data with the drms=19 kHz in the whole region. Comparison with the literature values from microwave and from far infrared measurements is made. An analogous analysis was carried out for the 12CH235Cl37Cl and 12CH237Cl2 species for which 4561 and 2465 transitions with Jmax=100, Kamax=19 and Jmax=88, Kamax=19 where assigned and analyzed. Sets of 20 fitted effective Hamiltonian parameters of 12CH235Cl37Cl and 15 fitted parameters of 12CH237Cl2 reproduce the assigned experimental transitions of the latter two isotopologues with the drms=20 kHz and drms=19 kHz, respectively and considerably improve the calculated line positions up to 1.1 THz in comparison with previous parameters.
