Generally we look for emission at submillimeter wavelengths, and for absorption at near infrared wavelengths. In the sub-mm typical opacities are ~ 0.01 cm 2 g-1.Since essentially no interstellar cloud has a surface density > 100 g cm-2, absorption of radiation from the back of the cloud by gas in front of it is completely negligible.

"WebThe interstellar gas clouds move along the field lines (because of the "frozen in" condition) and fall into the "wells" of the field. This causes further stretching of the magnetic field lines, making the "wells" deeper; thus large amounts of gas can fall into the "wells," creating large concentrations of gas, which then become gravitationally unstable ( Gorbatskii 1977 ).
