Abstract :
Some of the He-Ne and He-Xe laser lines in the infrared can be tuned within several gigahertz by applying an axial magnetic field. Stark patterns of vibration-rotation lines of organic molecules were observed at 3.36-, 3.39-, 3.50-, and 5.57-μm wavelengths. With applied Stark fields up to 50 kV/cm, many Stark components were resolved and some of the transitions of H2 CO, HDCO, and CH4 were definitely assigned. Molecular masers in the far infrared cannot be tuned over any appreciable range, but the Stark effects of the rotation lines of NH3 at two fixed far-infrared frequencies of the D2 O maser were observed. The observations of a Stark component of the 
line at 171.6 μm and the forbidden Stark components of the 
line at 84.1 μm are reported.
