Imitantikile ya COM iyasangwa mu ISM ilapeela amashiwi ayacindama pa lwa mipangilwe ya mipashi na, mu kupelako, ilyashi lya kale ilya makumbi ya molekyulu.
Ifilesangwa muli c-HCOOH asidi mu kati ka c-HCOOH ni 6% fye ifya muli c-HCOOH isomer, kabili intuntuko ya iko tayaishibikwe. Apa tulelondolola ukubapo kwa c-HCOOH mu makumbi ya fiko ayafiita ukupitila mu konaula no kucefyako kwa c-HCOOH na t-HCOOH mu nshita ya mipepele iyabikwamo HCOOH na ifiko ifingi nga HCO+ na NH3.
Twabomfeshe inshila ya ab initio iyakulishiwa ku kupenda amaka ya kwakanya aya c-HCOOH na t-HCOOH ukuputula / inshila sha kucingililamo. Imitantikile ya calo conse iyashintililwapo na ifishinka fya matabi fyapendelwe ukulingana na masambililo ya mibele ya calo iya kwaluka na umusango wa cipimo cikalamba mwi samba lya mibele ya ISM iyalinga.
HCOOH ilaonaika pa kulanshanya na HCO+ mu ciputulwa ca mwela pa kupanga ifiputulwa fitatu ifya HC (OH) 2+. Ama cation ayaishibikwa sana kuti yacita ifintu fimbi ifyaishibikwa mu ISM, pamo nga NH3, mu ciputulwa ca bubili ica kwalula c-HCOOH na t-HCOOH. Iyi inshila ilondolola imipangile ya c-HCOOH mu makumbi ya fiko ayafiita. Ukubika iyi nshila mu mano, umusango wa c-HCOOH ukulingana na t-HCOOH wali 25.7%.
Pa kulondolola ifyalandwapo 6% ifya kumona, tulefwaya ukutontonkanya pa nshila imbi iya konaula HCOOH cation. Inzila iyakonkana iya asidi-umushili (SAB) iyapeelwa muli uyu mulimo ilabikamo inshila iyayanguka iya ma molekyulu ayaishibikwa sana mu ISM.
Eico, HCOOH kuti yapita mu kwaluka uko twapingwilepo mwi samba lya mibele ya makumbi ya molekyulu ayafiita. Iyi ni nshila iipya mukati ka misango ya fimenwa ifya mweo mu ISM, iyo ingaesha ukulondolola ubupalamano pakati ka misango ya fimenwa ifya mweo ifisangwa mu ISM.
