Table 2 The frequencies of symmetric and asymmetric U-U stretching modes in U2@C60 and U2@C61 systems. All of these results were calculated at BP86/ANO_ECP60MWB~3-21G level
System | Symmetric U-U stretching | Asymmetric U-U stretching |
---|---|---|
U2@C60 | 162.9 | 157.2 |
U2@C61 (c, 9A′) | 127.4 | 142.0 |
