dc.description.abstractA Stark spectrometer and laser system has been developed which can measure Stark spectra of polar molecules with an absorptivity sensitivity of $a- 2 \times 10-9 cm^{-1}$. The accuracy for determining transition frequencies is about one MHz. The Stark plates are made of silvered glass, 60 cm long, spaced 0.05 cm. Stark fields to 60 KV/cm are used. The Stark field is square-wave modulated at 20 Hz. The detector is a Golay cell with quartz window and polyethylene lens optics. The laser is a direct discharge type, using HCN or DCN, at $1 = 337, 311, 195, 190 \mu m$. Source gases are cyanogen. $(CN)_{2}$, and $H_{2}$ or $D_{2}$, flowing about 10 std $cm^{3}$ per minute each. Plano-concave mirror geometry is used, $R_{c} = 8 m$. Inter-mirror distance is 3.7 meters; tube diameter = 10 cm. Mirrors are ground from OFHC copper. Spectral sensitivity is due primarily to stability of laser plasma, and to management of ``brown polymer'' deposit.en_US
