Its binding energy is about $130 cm^{-1}$ and the vdW stretch is $30 cm^{-1}$. The internal rotation of the complex is strongly coupled with the vdW stretch. Other conformers (two in-plane and one out-of-plane) have been identified as the $C_{3}$ moiety of the complex bends away from the equlibrium angle. The computation results will be used to qualitatively interpret our experimental observations. en_US dc.format.extent 143709 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.publisher Ohio State University en_US dc.title THE AB INITIO CALCULATION OF THE $C_{3}$ - AR VAN DER WAALS COMPLEX en_US dc.type article en_US
