I will present results of a program to map the distribution of molecular gas toward several well-known regions of massive star formation, and also selected nearby Bok Globules which are forming solar-mass stars. The maps show clear evidence of energy injection processes from stellar radiation, winds, and H II region expansion, in shaping and controlling the star formation process. Connections with infrared observations from the Spitzer Infrared Space Telescope will be emphasized. <br />
The observations were made with the Steward Observatory Heinrich Hertz Submillimeter Telescope. I will give a brief technical summary of the telescope and instrumentation used in our study.
