Ditekanyo tse di lemogilweng tsa di-isomer tsa COM mo ISM di tlamela ka tshedimosetso e e botlhokwa ka ga khemiseteri le fisikisi ya digase mme, kwa bofelong, hisitori ya maru a dimolekhule.
Diteng tsa esiti ya c-HCOOH mo gare ga konokono e e tsididi ke 6% fela ya diteng tsa isomer ya c-HCOOH, mme tshimologo ya yona ga e ise e itsiwe. Fano re tlhalosa go nna teng ga c-HCOOH mo marung a mantsho a dimolekhule ka go senngwa le go fokodiwa ga c-HCOOH le t-HCOOH ka nako ya dipotologo tse di akaretsang HCOOH le dimolekhule tse dintsi thata jaaka HCO+ le NH3.
Re dirisitse mokgwa o o atolositsweng wa ab initio go bala kabo e e ka nnang teng ya maatla a ditsela tsa c-HCOOH le t-HCOOH tsa go thubega/go tsamaya ka baesekele. Diphetogo tsa seelo sa lefatshe le dintlha tsa go tlhoma makala di ne tsa balelwa go ikaegilwe ka kgopolo ya puso ya phetogo le sebopego sa ikhweišene ya mong'a mo maemong a a tlwaelegileng a ISM.
HCOOH e a senngwa fa e dirisana le HCO+ mo legatong la gase go bopa di-isomer tse tharo tsa HC(OH)2+ cation. Di-cation tse di tlwaelegileng thata di ka tsiboga le dimolekhule tse dingwe tse di tlwaelegileng mo ISM, jaaka NH3, mo legatong la bobedi go fetola c-HCOOH le t-HCOOH. Mokgwa ono o tlhalosa go bopega ga c-HCOOH mo marung a mantsho a dimolekhule. Fa go tsewa tsia mokgwa ono, karolo ya c-HCOOH fa e bapisiwa le t-HCOOH e ne e le 25.7%.
Go tlhalosa 6% e e begilweng ya ditebelelo, re tshitshinya go akanyetsa mokgwa o o oketsegileng wa go senya kation ya HCOOH. Mokgwa wa tatelano wa asiti-motheo (SAB) o o tshitshintsweng mo tirong eno o akaretsa thulaganyo e e bonako ya dimolekhule tse di tlwaelegileng thata mo ISM.
Ka jalo, go ka direga gore HCOOH e nne le phetogo e re e tshitshintseng mo maemong a maru a a lefifi a dimolekhule. Se ke mokgwa o mošwa mo teng ga isomerism ya dimolekhule tsa ditshedi mo ISM, e e ka lekang go tlhalosa dikamano magareng ga di-isomer tsa dimolekhule tsa ditshedi tse di fitlhelwang mo ISM.
