We present a survey in the spectral region of 200-700 cm
-1(

m) of pulsed mirrorless gas lasers pumped by a TEA CO
2laser. 55 lines are found covering the wavelength range 15.8-57 cm
-1in the gases NH
3,
15NH
3, D
2O, CH
3OH, CD
3OH, and CD
3OD. Most of these lines are reported for the first time. One of the strongest lines (26.4 μm in NH
3) emits a considerable pulse energy of 100 mJ. No lines were found in C
