NH/sub 3/ (1,1) and (2,2) line emission spectra were measured in the DR 21(0H) region and in a new NH/sub 3/ region in NGC 2264. Hyperfine structure of the (1,1) transition was resolved, providing data on optical depth and excitation temperature for calculation of column densities and kinetic temperatures. (auth)
