Bunji bwa COM isomers bwakabonwa mu ISM bupa makani aayandika aatala a chemistry a physics yamagesi, mpawo kumamanino, makani aakaindi aa kkumbi lya molecule.
Bunji bwa c-HCOOH acid mukati kakutontola buli buyo a 6% ya mweelwe wa c-HCOOH isomer, ooko nkwazwa takuzyibidwe pe. Aawa tulapandulula kujanika kwa c-HCOOH mumakumbi aama molecule aasiya kwiinda mukunyonyoonwa akukazya kupanga c-HCOOH a t-HCOOH muchiindi chakuzungaana kwa HCOOH ama molecule miingi loko mbuli HCO+ a NH3.
Twakabelesya nzila ya ab initio iisumpukide kuti tubone nguzu zya c-HCOOH antoomwe a t-HCOOH nzila zyakutyoka/kupanga. Imweelwe wanyika yoonse uutacinci antoomwe azintu zipa kuti kube mitabi zyakabalilwa kweendelanya anjiisyo yachiimo chakusanduka anzila ya equation mpati mubukkale bwa ISM.
Kunyonyoonwa kwa HCOOH kwiinda mukuswaangana a HCO+ muchiimo cha gasi kuletela ma isomers otatwe aa HC(OH)2+ cation. Ma cations aadumide alakonzya kuswaangana ama molecule amwi aa ISM mbuli NH3 munzila yabili kuti apiluke kuba c-HCOOH antoomwe a t-HCOOH. Eeyi nzila ipandulula kupangwa kwa c-HCOOH mumakumbi aasiyidwe. Kulanga nzila eeyi, mweelwe wa c-HCOOH kweendelana a t-HCOOH wakali 25.7%.
Kupandulula 6% yakabonwa, twayeeya kuti tulangisisye nzila zimbi zyakunyonyoona HCOOH cation. Nzila ya sequential acid-base (SAB) yakaambwa mumulimo ooyu ibikkilizya nzila yakufwambaana yama molecule iidumide kapati mu ISM.
Aboobo, HCOOH ilalangilwa kwiinda mukusanduka nkotwakayeeya mubukkale bwamakumbi aamudima. Eeyi ninzila mpya mukati ka isomerization ya organic molecules mu ISM, ilakonzya kusola kupandulula kujatana aakati ka isomers ya organic molecules iijanika mu ISM.
