The broadening coefficients and shifts and Dicke narrowing will be compared with prior laser measurements in the Q branch of this $band^{1}$ as well as previous FTIR measurements in the P and R $branches^{2}$. We will also address the question of line mixing between the overlapping tetrahedral components in a given blended J manifold as reported by the NASA Langley $group^{3}$. en_US dc.format.extent 46149 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.publisher Ohio State University en_US dc.title $N_{2}$ AND Ar BROADENING OF THE P AND R BRANCHES OF THE $\nu_{3}$ BAND OF METHANE en_US dc.type article en_US
