摘要
We have determined the spectroscopic parameters that are necessary to describe accurately the R(0) line profile of the CH(4)2nu(3) band from about 1 Torr to a few hundred Torr of pure CH4. The intensities determined at each pressure are in overall agreement to better than 0.7%. The R(3) manifold of the same band has also been investigated. Relative positions and absolute intensities of the three transitions composing the triplet have been determined. The intensity distribution inside the triplet is in fair agreement with recent theoretical predictions, (C) 2002 Elsevier Science (USA).
