The rotational distortion constants have also been calculated for these molecules from the potential energy constants, and the shrinkage effects in the internuclear distances have been determined. The mean square amplitudes in {\AA}$^{2}$ for $CF_{4}, CCI_{4}$, and $CBr_{4}$ are respectively: 0.001876, 0.002484, and 0.002643 for $\sigma_{r} (C-X)$, where $X=F,$CL, or Br; and 0.002936, 0.004636, and 0.005877 for $\sigma_{d} (X\ldots X)$. The $D^{J}$ values for $CF_{4}, CCI_{4}$, and $CBr_{4}$ are respectively 1650, 176.7, and 26.5 c/s. The corresponding $D_{J_{r}}$ values are 1156, 132.9, and 21.1 c/s.” en_US dc.format.extent 100219 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.publisher Ohio State University en_US dc.title MEAN AMPLITUDES, ROTATIONAL DISTORTION CONSTANTS, AND SHRINKAGE EFFECTS FOR $CF_{4}$, $CCl_{4}$ AND $CBr_{4}$ en_US dc.type article en_US
