請問各位大俠,“the heavier atoms”翻譯過來是“重原子”的意思嗎?還有哪些原子是the heavier atoms?再是“ all-electron”又是什么意思? 還請各位大俠幫忙看看你,謝謝! |

In general we recommend the use of frozen core basis sets if available. Especially for “the heavier atoms” the number of functions is much smaller than for their “all-electron” counterparts. Our tests indicate that the error made by invoking the frozen core approximation is usually clearly smaller than the difference with respect to slightly higher quality basis sets. For the ZORA/QZ4P basis sets, only all-electron basis sets are available as these are intended for near basis set limit calculations only in which the CPU time is not a major concern |
