Abstract: Polarimetry in the submillimeter is the most effective probe of magnetic fields in star-forming regions. Linearly polarized emission is detected from dust on all scales and at all wavelengths observed in molecular clouds. Linear polarization of CO has been detected in several outflows and even in the envelope of a high mass core. This method gives access to the field geometry in environments inaccessible via dust polarimetry. I discuss primarily the results from the SCUBA and Hertz polarimeters and the BIMA array. I also discuss the spectroscopic technique of estimation of the magnetic field inclination to the line of sight by comparison of ionic and neutral field lines. Without requiring a polarimeter, this method has the potential of greatly expanding the impact of polarimetric data. Finally, I summarize the potential of future polarimeters to further expand our understanding of the role of the magnetic field in star formation and molecular cloud processes.
