Abstract
We describe the initial phase of a long path terahertz time-domain spectroscopy apparatus to detect THz rotational spectra of small vapor phase molecules within the atmospheric transparency windows. We discuss the measurements first for a relatively short path THz propagation path of 6.2 meters, and then for a much longer path of 170 meters.
