The N[sub 2]H[sub 4] (hydrazine) molecule is a slightly asymmetric top and has a fairly large electric dipole moment of 1.8 Debye. Also, its infrared spectrum shows strong vibrational absorption bands in the frequency range covered by CO[sub 2] lasers. These attributes make N[sub 2]H[sub 4] a good lasing medium for CO[sub 2] laser pumped far-infrared (FIR) lasers. N[sub 2]H[sub 4] is an efficient optically pumped FIR laser, with 52 reported laser lines. The frequencies of about 40% of these have been measured. Here, measurements have been made for 32 far infrared laser frequencies of optically pumped hydrazine, 30 of which are new. The wavelengths range from 95 to 528 [mu]m. A pair of frequency-stabilized CO[sub 2] lasers were used as standards for the heterodyne frequency measurements. One of the lines can be used as a local oscillator for astronomical searches for [sup 14]N[sup +], and other lines can be used to study transitions in metastable Ca.
