Through interactions with light and with each other, molecules provide valuable insight into the physical conditions, composition, distribution and evolution of material in interstellar clouds and star-forming regions. Complementary infrared and submillimeter observations of AFGL 2591, AFGL 490 and NGC 2024 are presented as a portion of a larger observational sample of dark star-forming clouds. This comprehensive spectroscopic study allows the direct measurement of H_2, H_3(+) , (12) CO and (13) CO via infrared absorption line spectroscopy along identical pencil-beam lines of sight toward obscured YSO's. Submillimeter-wave emission line techniques permit large scale mapping of the environments of star formation through CO, its rare isotopes, and photodissociated CI emission. Observations of CH_3OH, and vibrationally excited HCN and CS make sensitive probes of the hot molecular gas in these regions. Detections of reactive ions such as HCO(+) , N_2H(+) and H_3O(+) are discussed in the light of the measured H_3(+) abundances and estimated cosmic ray ionization rates in dense clouds. This study highlights the value of multiwavelength studies in deciphering the structure and evolution of molecular clouds and star-forming regions.
