摘要
The angular distributions of C-H ... O interactions for different types of C-H groups show that the directionality decreases with decreasing C-H polarisation, but that it is still clearly recognisable for methyl groups; for C-H ... H-C van der Waals contacts, in contrast, isotropic angular characteristics are observed.
