chemfig 및 tikzpicture가 있는 갈래 화살표

이 질문은 다음 링크에서 요청되었습니다.Chemfig가 있는 갈래 화살 그것은 나에게 매우 도움이 됩니다. 해결책을 제시해준 Gonzalo Medina에게 감사를 전하고 싶습니다. 그러나 어디에서도 해결책을 찾을 수 없는 두 가지 질문이 있습니다.

1) tikzpicture 내에서 \chemfig가 올바르게 작동하도록 하는 방법은 무엇입니까? 화살표 위와 아래에 화학 구조(chemfig로 그린)를 갖고 싶습니다. 그러나 \chemfig{...}모든 채권을 사용하면 화살표로 변합니다. 이 명령이 명령 안에 있기 때문인 것 같아요 \draw.

2) 화살표 위/아래 노드의 내용에 맞게 화살표 부분(여전히 동일한 선)의 길이만 변경하려면 어떻게 해야 합니까?

내가 만들고 싶은 계획은 다음과 같습니다.여기에 이미지 설명을 입력하세요

엄청 고마워!

내 tex 파일은 다음과 같습니다.

답변1

1) 여기서는 "선 그리기" 명령에서 화살표 머리를 "제거"하기 위해 명령 [-]에 선택적 인수를 추가하기만 하면 됩니다 .\chemfig

2) 여기서는 "수동으로" 수행하는 것이 좋습니다. 먼저 기능을 사용하여 최상위 노드를 배치한 =<number>cm and <number>cm of <node>다음 생성된 \split변수를 사용하여 이 노드에 대한 경로를 "분할"해야 하는지 결정하고 생성된 \xshift변수를 사용하여 화살표 위와 아래에 배치되는 노드의 오프셋을 결정합니다. 반응 구성표를 그리는 동안 오른쪽의 노드 위치를 조정하거나 \split필요에 맞게 비율을 조정하여 간단히 조정할 수 있습니다.
