Object of research: molecules furfural, an atmosphere, ozone, ethylene, threechlorethylene. The purpose of work: 1. Modernization of a submillimetric spectrometer and trace CO2-lidar. 2. Experimental and theoretical researches of rotation spectrums of molecules of furfurol in the basic and the excited vibrational states. 3. Measurements of concentration of ozone, ethylene and threechlorethylene above a Kharkov during the spring-autumn period. The radiospectrometer for investigations of the rotational spectra of molecules is modernized. The new design and successful installation of the block of 3-rd ring FАEF has allowed to reduce in some times which has sharply increased stability of its work. The new program of processing of spectrograms was developed and introduced. Records of lines of absorption and measurement of resonant frequencies of molecules C4H3OCHO (furfurol) in a frequency band from 47 up to 330 GHz in basic and the first torsion a states are lead. The analysis of spectrums of two conformer in the basic and in the first torsion a vibrational state with use of a Hamiltonian of Watson has enabled to find constants of a Hamiltonian which with a high accuracy describe the rotation spectrum of molecules of furfurol in a range of millimeter and submillimeter lengths of waves. Modernization trace CO2-lidar with the purpose of its automation. Scheduled regular measurements of concentration of ozone in the centre of Kharkov by means of trace CO2-lidars in 2006-2008 р. during time from April, 10th till September, 25th, and also ethylene and threechlorethylene from April, 14th till May, 20th, 2008 are lead.
