Purpose of the work is to provide necessary supporting information for the spectra of these molecules for the radio astronomical observations of interstellar space. The research method is the experimental measurement of the molecular spectra in the gas phase followed by analysis using corresponding quantum-mechanical models. The results of the second year of the joint research project NAS of Ukraine - CNRS (France) are presented. Experimental and theoretical investigations of submillimeter spectra of following astrophysical molecules have been carried out: N-methylformamide (CH3NHCHO), 1,3-propanediol (CH2(CH2OH)2), propionamide (CH3CH2C=O(NH2)), propionic acid (CH3CH2COOH) and deuterated methylamines (CH3ND2, CH3NHD). Spectra of N-methylformamide, propionamide and propionic acid were analyzed using the Rho axis method, spectra of 1,3-propanediol and deuterated methylamines were analyzed using the high-barrier tunneling formalism. Also the investigation of the spectra of 13C isotopomers of acetaldehyde (13CH312CHO, 12CH313CHO) and methylformate (HCOOCH3), which was started at the first year of the project, was continued. The mutual visits of experts from France and Ukraine were organized with the aim of joint research, data processing and preparation of joint publications.
