A search for NH3 emission towards galactic HII regions NGC 6334, Orion and G 328.2-0.5 was undertaken. All observations were made at frequencies which correspond to the rotational transitions (J,K) = (1,1), (2,2) and (3,3). The observational parameters (antenna temperature, line width, etc.) were utilized to derive the physical parameters of the HII regions such as ammonia column density, molecular hydrogen density, etc. Based on these results we discussed the estimated kinetic temperature of these regions as well as the mass of the molecular cloud viewed by the antenna beam. This work also presents the results of first detection NH3 in the direction of the source G 328.2-0.5.
