Scientific paper

In this paper we briefly analyze the type of molecular transitions and the contribution of polyatomic molecules to the Far-Infrared spectrum of interstellar and circumstellar clouds. For that aim, we present our recent work on molecular first Far-IR detections. All the results presented here were taken in the direction of Sgr B2, close to the Galactic Center. Our study is based on Fabry-Perot observations carried out with the Infrared Space Observatory (ISO) Long Wavelength Spectrometer (LWS). In addition, we report our last Far-IR and millimeter observations of water vapour. This incorporates several thermal ortho/para-H2O transitions and ground-based observations of the 313-220 maser transition at 183.31 GHz. Our first Far-IR identifications include molecules such as NH, NH2, C3, H3O+. They mainly represent the whole types of molecular transitions likely to occur in molecular clouds Far-IR spectra. In addition to traze the dense gas with never observed before molecular transitions, this work represents a preparatory study for the spectroscopy programs that could be done with FIRST in the Far-IR.
