나는 chemfig를 사용하여 다음과 같은 반응식을 그리려고 노력해 왔습니다.
여기에 제공된 응답을 따르십시오.chemfig: 이중 작살 + 아치형 내부/외부 화살표 반응, 나는 다음과 같은 구성표를 그렸습니다.
다음과 같이 정의된 화살표를 사용합니다 <U=>
.

\definearrow2{<U=>}{%
\CF@arrow@shift@nodes{#2}%
\path[allow upside down](\CF@arrow@start@node)--(\CF@arrow@end@node)%
node[pos=0,yshift=1pt](\CF@arrow@start@node @u0){}%
node[pos=0,yshift=-1pt](\CF@arrow@start@node @d0){}%

지금쯤 눈치채셨겠지만 속도 상수 w
와 가 누락되었습니다 z
. 화살표의 정의를 수정하려고 시도했지만 <U=>
아직 완전한 다이어그램을 만들 수 없었습니다. 다음은 완전히 작동하는 예입니다.
