Emazinga labonwako e-COM isomers ku-ISM aniketa lwati lolubalulekile mayelana nekhemikhali kanye ne-physics yemagesi futsi, ekugcineni, umlandvo wemafu emamolekhyuli.
Lokucuketfwe yi c-HCOOH acid ku core lebandzako ngu 6% kuphela wekucuketfwe kwe c-HCOOH isomer, futsi imvelaphi yayo ihlala ingatiwa. Lapha sichaza kubakhona kwe c-HCOOH emafini lamnyama ema molecule ngekubhujiswa kanye nekuncishiswa kwe c-HCOOH kanye ne t-HCOOH ngesikhatsi semijikeleto lefaka ekhatsi iHCOOH kanye nema molecule lamanyenti kakhulu lafana ne HCO+ kanye ne NH3.
Sisebentise indlela ye-ab initio lendze kubala kusakateka kwemandla langaba khona kwetindlela tekuphuka/tekuhamba ngebhayisikili te-c-HCOOH kanye ne-t-HCOOH. Tintfo letingagucuki telizinga lemhlaba wonkhe kanye netizatfu tekukhicita emagatja kwabalwa ngekusebentisa ithiyori yesimo sekugucuka kanye nesimo se-equation lenkhulu ngaphansi kwetimo letijwayelekile te-ISM.
I-HCOOH iyabhujiswa ngesikhatsi ihlangana ne-HCO+ esigabeni segesi kwenta ema-isomer lamatsatfu e-HC(OH)2+ cation. Ema cations lavame kakhulu angahlangana naletinye tintfo letivamile ku ISM, njenge NH3, esinyatselweni sesibili sekugucula i-c-HCOOH ne-t-HCOOH. Lendlela ichaza kwakheka kwe-c-HCOOH emafini lamnyama emamolekhyuli. Kutsatsa lendlela, inani le-c-HCOOH lelihlobene ne-t-HCOOH lalingu-25.7%.
Kuchaza lokubikwe 6% lokubonwako, siphakamisa kutsi sicabangele indlela lengetiwe yekubhujiswa kwe-HCOOH cation. Indlela yekulandzelana ye-acid-base (SAB) lephakanyiswe kulomsebenti ifaka ekhatsi inchubo lesheshako yemamolekhyuli levame kakhulu ku-ISM.
Ngako-ke, i-HCOOH kungenteka kutsi ibhekane nekugucuka lesiphakamisile ngaphansi kwetimo temafu e-molecule lamnyama. Lena yindlela lensha ngaphakatsi kwe isomerism yetintfo letiphilako ku ISM, lekungazama kuchaza budlelwane emkhatsini wema isomers etintfo letiphilako letitfolakala ku ISM.
