Paper Abstract

At submillimeter wavelengths, broadband spectroscopy is currently possible only with a Fourier transform spectrometer (FTS). As a result, FTSes are quite useful for observations of objects in which spectral lines either cover a large frequency range, or where lines are broadened either by pressure or kinematics. Sources matching these descriptions include galaxies, hot, dense cores in interstellar molecular clouds, and planetary atmospheres. In the following, a tour of the classes of observations enabled by broadband spectroscopy is presented. As meaningful results call for attention to calibration, relevant calibration issues are discussed in the context of these observations.
