Abstract
THE investigation of far infra-red stimulated emission sources at the National Physical Laboratory continues, and some results obtained using hydrogen cyanide and related molecules in pulsed electrical discharges are reported here. The interest attaching to these results is in the long wave-length of the emission and particularly its relation to the wave-length of water vapour absorption lines in the atmosphere.
