New N/sub 2/H/sub 4/ far infrared laser lines and frequencies

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 /spl 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.<
