Photoabsorption and photodissociation of molecules important in the interstellar medium [PDF]
Photoabsorption and fluorescence cross sections of molecules important in the interstellar medium were measured in the 90 to 200 nm region using synchrotron radiation, excimer laser, and condensed discharge lamps as light sources.

The Young Ages of 70 μm Dark Clumps Inferred from Carbon Chain Chemistry
The Astrophysical JournalThe physical conditions of the earliest environment of high-mass star formation are currently poorly understood. To that end, we present observations of the carbon chain molecules HC _5 N, CCS, and HC _7 N in the 22–25 GHz band toward 12 high-mass 70 μ m

Molecules, grains, and shocks: A comparison of CO, H I, and IRAS data [PDF]
The IR and H I properties, and CO content were compared for a set of 26 isolated, degree-sized interstellar clouds. The comparisons offer some conclusions concerning the effects of kinematics on molecular content and grain size distribution.

Numerical studies of collapsing interstellar clouds [PDF]
Numerical simulation of the structure and evolution of interstellar clouds was initiated. Steps were taken toward an integrated treatment of the dynamical, thermal, and chemical processes entering model calculations.
