Summary:Title screen
The high-resolution submillimeter-wave spectra of methylene chloride (recorded in Germany and France in the region of 0.075–1.1 THz) were analyzed to describe the quadrupole-rotational structures of the 12CH235Cl37Cl species in the (v = 1) and (v = 2) vibrational states. Analysis was made using Watson’s Hamiltonian in A-reduction and Ir representation with the ASYMTOPTPU code and SPFIT/SPCAT package. The study assigned 4983 lines for the (v = 1) state and 842 lines for the (v = 2) state. Weighted fit of the rotational, centrifugal distortion, and quadrupole splitting parameters was performed, reproducing experimental positions with rms = 21/26 kHz. The results show significant improvement over previously known literature parameters
