MoleculeSubstructureCount

MoleculeSubstructureCount[mol,patt]

给出 patt 以子结构出现在 as a substructure in mol 中的次数计数.

MoleculeSubstructureCount[patt]

表示可以应用于分子的 MoleculeSubstructureCount 的操作符形式.

更多信息和选项

  • patt 应为下列形式之一:
  • MoleculePattern[]分子模式
    Atom[]单原子模式
    Bond[{a1,a2}]有指定模式的原子间的键
  • 默认情况下,通过移除与同一组原子的多个匹配精简子结构匹配. 使用选项 Overlaps->True 可禁用这一功能.
