Abstract

For the bent T-shaped benzene dimer, the vibrational frequencies at the MP2/aug-cc-pVDZ level with counterpoise correction reproduce experimental results of the small "red shifts" of C-H stretching, while those without counterpoise correction yield considerable "blue shift." Counterpoise correction also affects the C-H bond distances of C-H⋯π interactions as well as intermoiety distances. © 2009 American Institute of Physics.
