Detection of the vapor of asymmetric dimethyl hydrazine in the atmosphere by the method of spectrophotometry in the near IR range

We proposed and tested a method of detecting and determining the content of asymmetric dimethylhydrazine (ADMH) in the atmosphere based on measuring the absorption spectra in the near IR spectral region. The method is shown to permit confident diagnostics of the presence of an ADMH cloud in the atmosphere with a concentration of several maximum permissible concentrations (MPC). A. N.
