Sebopeho sa kristale sa acetic acid se bontša hore limolek'hule li kopantsoe ho dimers (tse tsejoang hape e le dimers) ka li-hydrogen bonds, 'me li-dimers li boetse li teng sebakeng sa mouoane ho 120 ° C. Dimers li na le botsitso bo phahameng, 'me ho ipakile hore carboxylic li-acids tse nang le boima bo tlase ba limolek'hule tse kang formic acid le acetic acid li teng ka mokhoa oa dimers sebakeng se tiileng, sa metsi kapa sa gase ka mokhoa oa ho fumana boima ba limolek'hule ka ho fokotsa ntlha ea leqhoa le X-ray diffraction.Ha acetic acid e qhibiliha ka metsi, maqhama a hydrogen pakeng tsa dimers a robeha kapele.Li-carboxylic acid tse ling li bonts'a dimerization e tšoanang.
