  Abstract: Sublimation of ice from comets can reveal clues to the interior of the comet, provide insights on the formation of our solar system, and reveal interesting dynamical processes in a rarefied atmosphere. Water is the primary volatile in comet nuclear ices, but may be difficult to observe through Earth's atmosphere. As an immediate product of water molecule breakup, OH is easily observed at radio wavelengths and can be used to trace other gas phenomena in comets. We will review gas production rates, outflow velocities, and other physical processes as revealed by a 15-year survey of 18-cm OH spectra from dozens of comets, and the unique elements of computational modelling for data analysis.
