dc.description.abstractA description is given of experiments performed or completed during the past year. The partial resolving of the hyperfine structure of the J = 0 $\rightarrow$ l. v=0 rotational transition of `Lich’F has been performed in an electric resonance molecular beam apparatus. The Stark effects of $O_{2}$ and $H_{2} S$ have been completed, and the dipole moment of $H_{2} O$ has been re-evaluated on the basis of new measurements. Techniques for obtaining far infrared frequency standard markers have been established by the phaselocking of an HCN laser to a harmonic of a radio frequency standard. The stability of the heterodyne beat between the RF standard and the HCN laser is on the order of parts in $10^{10}-$$10^{11}$ and has a 5 Hz linewidth at 890 GHz. A survey of far infrared coherent spectroscopic techniques which are being investigated will be given. Tunable sources for spectroscopic applications will be discussed with a description of the applications of a tunable source consisting of a $CO_{2}$ laser mixed with a millimeter wave klystron. Gain measurements have been performed on the rotation-vibration transitions of the CO laser in the 5.0--6.0 micron wavelength, and the results interpreted in terms of molecular energy transfer.en_US
