  We present results of a spectral survey towards a dense molecular
condensation and young stellar objects (YSOs) projected on the border of the
HII region RCW 120 and discuss emission of 20 molecules which produce the
brightest lines. The survey was performed with the APEX telescope in the
frequency range 200 -- 260 GHz. We provide evidences for two outflows in the
dense gas. The first one is powered by the RCW 120 S2 YSO and oriented along
the line of sight. The second outflow around RCW 120 S1 is aligned almost
perpendicular to the line of sight. We show that area with bright emission of
CH$_3$OH, CH$_3$CCH and CH$_3$CN are organised into an onion-like structure
where CH$_3$CN traces warmer regions around the YSOs than the other molecules.
Methanol seems to be released to the gas phase by shock waves in the vicinity
of the outflows while thermal evaporation still does not work towards the YSOs.
We find only a single manifestation of the UV radiation to the molecules,
namely, enhanced abundances of small hydrocarbons CCH and c-C$_3$H$_2$ in the
photo-dissociation region.
