Abstract

High-resolution Fourier transform infrared spectra of natural CF3Cl (Freon-13) have been recorded in the region around 1890 cm(-1) with the purpose of analyzing the nu(1) + nu(2) combination band. The K structure of the P(J) and R(J) manifolds was resolved and identified; the assignment of the rovibrational transitions was extended up to J = 75, K = 36 for (CF3Cl)-Cl-35 and up to J = 50, K = 27 for (CF3Cl)-Cl-37. More than 1700 and 200 lines for (CF3Cl)-Cl-35 and (CF3Cl)-Cl-37, respectively, were analyzed by a least-squares procedure and reliable spectroscopic parameters were determined for both the isotopomers. Additionally, for the (CF3Cl)-Cl-35 species, the J clusters of the nu(1) + nu(2) + nu(6) - nu(6) hot band have been observed and analyzed by a fourth-order polynomial fit.
