Abstract
Observations of the NH3 (1, 1) and (2, 2) inversion transitions made with a 2.3-arcmin beam reveal the molecular cloud G35.2 – 0.74 to possess an interesting velocity structure. To the north, near an H2O maser, the source is observed as a single component. To the south, around a red nebulosity, the NH3 spectra are split into two components with a separation 3 km s–1. This splitting is of significance because it represents very clear evidence that, in this cloud at least, systematic velocity motion is an important factor in determining the observed velocity dispersion.Keywords
