Saamiyada tirada badan ee la arkay ee isomers-ka COM ee ku jira ISM waxay bixiyaan macluumaad qiimo leh oo ku saabsan kiimikada iyo fiisigiska gaasaska iyo, ugu dambeyntii, taariikhda daruuraha molecular-ka.
Waxa ku jira aashitada c-HCOOH ee ku jirta xudunta qabow waa 6% oo keliya xaddiga isomer-ka c-HCOOH, kaas oo aan weli la garanayn asalka uu ka soo jeedo. Halkan waxaan ku sharxeynaa joogitaanka c-HCOOH ee daruuraha molecular-ka ee mugdiga ah iyadoo la burburinayo lana hortagayo sameynta c-HCOOH iyo t-HCOOH inta lagu jiro geedi socod wareeg ah oo ay ku jiraan HCOOH iyo molecules aad u tiro badan sida HCO+ iyo NH3.
Waxaan isticmaalnay hab ab initio oo horumarsan si aan u xisaabinno qaybinta tamarta ee suurtagalka ah ee waddooyinka kala-goynta/samaynta wareegyada c-HCOOH iyo t-HCOOH. Joogtaynta heerka caalamiga ah iyo arrimaha laanta waxaa lagu xisaabiyay iyadoo lagu saleynayo aragtida xaaladda kala-guurka iyo qaabka isle'egta sare ee xaaladaha caadiga ah ee ISM.
Burburka HCOOH ee ka dhasha falgalka HCO+ marxaladda gaaska wuxuu horseedaa saddex isomers oo ka mid ah cation-ka HC(OH)2+. Katamiinnada ugu badan waxay la falgeli karaan molecules-ka kale ee caadiga ah ee ISM sida NH3 tallaabada labaad si ay dib ugu noqdaan c-HCOOH iyo t-HCOOH. Habkani wuxuu sharxayaa sameynta c-HCOOH ee daruuraha molecular-ka ee mugdiga ah. Iyadoo la tixgelinayo habkan, saamiga c-HCOOH marka loo eego t-HCOOH wuxuu ahaa 25.7%.
Si loo sharaxo 6% ee la arkay, waxaan soo jeedinaynaa in la tixgeliyo farsamooyin dheeraad ah oo loogu talagalay burburinta cation-ka HCOOH. Habka salka aashitada ee isku xigxiga (SAB) ee lagu soo jeediyay shaqadan waxaa ku jira geeddi-socod degdeg ah oo molecules ah oo aad ugu badan ISM.
Sidaa darteed, HCOOH waxay u badan tahay inay mari doonto isbeddelka aan soo jeedinay iyadoo la raacayo xaaladaha daruuraha molecular-ka ee mugdiga ah. Tani waa hab cusub oo ku jira kala soocidda molecules-ka organic-ga ah ee ISM, taasoo laga yaabo inay isku daydo inay sharaxdo xiriirka ka dhexeeya isomers-ka molecules-ka organic-ga ah ee laga helo ISM.
