Emigerageranyo gy’obungi obwetegerezeddwa obwa COM isomers mu ISM giwa amawulire ag’omuwendo agakwata ku kemiko ne fizikisi ya ggaasi era, ku nkomerero, ebyafaayo by’ekire kya molekyu.
Ebirimu asidi wa c-HCOOH mu kitundu ekinyogovu biri ebitundu 6% byokka ku bungi bwa c-HCOOH isomer, ensibuko yaayo temanyiddwa. Wano tunnyonnyola okubeerawo kwa c-HCOOH mu bire bya molekyu enzirugavu nga tusaanyaawo n’okuziyiza okutondebwa kwa c-HCOOH ne t-HCOOH mu nkola y’okutambula nga mulimu HCOOH ne molekyo nnyingi nnyo nga HCO+ ne NH3.
Twakozesa enkola ya ab initio ey’omulembe okubala engabanya y’amasoboza agayinza okubaawo mu makubo g’okumenya/okutondebwa kw’enzirukanya ya c-HCOOH ne t-HCOOH. Enkyukakyuka z’omutindo gw’ensi yonna n’ensonga z’amatabi byabalirirwa okusinziira ku ndowooza y’embeera y’enkyukakyuka n’engeri y’ennyingo enkulu wansi w’embeera za ISM eza bulijjo.
Okusaanawo kwa HCOOH nga tukwatagana ne HCO+ mu kitundu kya ggaasi kivaamu isomers ssatu eza HC(OH)2+ cation. Cations ezisinga okubeerawo zisobola okukolagana ne molekyo za ISM endala eza bulijjo nga NH3 mu mutendera ogwokubiri ne zikola okudda mu c-HCOOH ne t-HCOOH. Enkola eno ennyonnyola okutondebwa kwa c-HCOOH mu bire bya molekyu enzirugavu. Nga tutwala enkola eno mu nkola, ekitundu kya c-HCOOH okusinziira ku t-HCOOH kyali 25.7%.
Okunnyonnyola ebitundu 6% ebyetegereza, tuteesa okulowooza ku nkola endala ez’okusaanyaawo cation ya HCOOH. Enkola ya sequential acid-base (SAB) eteeseddwa mu mulimu guno erimu enkola ey’amangu eya molekyo etera ennyo mu ISM.
N’olwekyo, HCOOH eyolekedde okuyita mu nkyukakyuka gye twateesa wansi w’embeera z’ebire bya molekyu enzirugavu. Eno nkola mpya munda mu isomerization ya molekyo z’ebiramu mu ISM, eyinza okugezaako okunnyonnyola enkolagana wakati wa isomers za molekyo z’ebiramu ezisangibwa mu ISM.
