摘要: The capabilities of the travelling-wave spectrometry in field high-resolution measurements low-pressure gases at microwave frequencies are discussed. Some details about main aspects experimental procedure and data management, useful for improvement overall performances, specified. A pressure broadening (72.5±1.5) MHz/Torr a shift (4.3±0.3) measured J=1−0 rotational line CH3C14N. These results more accurate than those previously reported better agreement with theoretical predictions.
