Abstract
Most molecules of astrophysical, chemical, and environmental importance exhibit strong maxima in their interaction strengths with electromagnetic radiation in the millimeter and sub-millimeter spectral range. Over the past decade or so, we have developed the \underline{Fa}st \underline{S}can \underline{S}ubmillimeter \underline{S}pectroscopic \underline{T}echnique (FASSST) } } , which makes possible rapid interrogation of a large number of ro-vibrational transitions. We have also developed automated approaches for the analysis of the resulting large spectral data sets, most notable of these being CAAARS } (\underline{C}omputer \underline{A}ided \underline{A}ssignment of \underline{A}symmetric \underline{R}otor \underline{S}pectra). This work has been a process of continual enhancement of both hardware and software. In this talk we will describe the current state-of-the art for this hardware/software combination, recent extensions, and potential future enhancements. This will include a multiplier based extension of the spectral range based on the more well behaved lower frequency BWOs. Recent spectroscopic work will be used to illustrate the characteristics of the system.
