Ibipimo by’ubwinshi bwa isomeri za COM byagaragaye muri ISM bitanga amakuru y’ingirakamaro ku bijyanye na chimie na fiziki y’imyuka, ndetse n’amateka y’igicu cy’uturemangingo.
Ingano ya aside c-HCOOH mu gice cy'imbere cy'umubiri ni 6% gusa by'ingano ya isomer ya c-HCOOH, aho inkomoko yayo itazwi neza. Aha turasobanura ko c-HCOOH iri mu bicu byijimye bya molekile bitewe no gusenya no kurwanya ishingwa rya c-HCOOH na t-HCOOH mu gihe cy'urugendo rw'imizunguruko rukoresha HCOOH n'utunyangingo twinshi cyane nka HCO+ na NH3.
Twakoresheje uburyo bugezweho bwa ab initio kugira ngo tubare ikwirakwizwa ry'ingufu rishoboka rya c-HCOOH na t-HCOOH mu buryo bwo kugabanya/guteranya imbaraga. Ibipimo rusange by'umuvuduko n'ibipimo by'amashami byabazwe hashingiwe ku nyigisho y'impinduka n'imiterere y'ikigereranyo gikuru mu bihe bisanzwe bya ISM.
Gusenyuka kwa HCOOH binyuze mu gukorana na HCO+ mu gice cya gaze bitera isomeri eshatu za HC(OH)2+. Cations zikunze gukoreshwa cyane zishobora gukorana n'izindi molekile zisanzwe za ISM nka NH3 mu ntambwe ya kabiri kugira ngo zisubire kuri c-HCOOH na t-HCOOH. Ubu buryo busobanura ikorwa rya c-HCOOH mu bicu byijimye bya molekile. Dukurikije ubu buryo, igipimo cya c-HCOOH ugereranyije na t-HCOOH cyari 25.7%.
Kugira ngo dusobanure 6% byagaragaye, turasaba gusuzuma ubundi buryo bwo gusenya HCOOH cation. Uburyo bwa sequential aside-base (SAB) bwatanzwe muri iki gitabo bukubiyemo inzira yihuta ya molekile zikunze kugaragara cyane muri ISM.
Bityo rero, HCOOH ishobora kunyura mu mpinduka twatanze mu gihe cy'ibicu byijimye bya molekile. Ubu ni uburyo bushya bwo gusesengura molekile za organic muri ISM, bushobora kugerageza gusobanura isano iri hagati ya isomers za molekile za organic ziboneka muri ISM.
