Ibipimo bya COM isomers byagaragaye muri ISM bitanga amakuru y'ingirakamaro ku bijyanye na chimie na fiziki y'imyuka, ndetse n'amateka y'ibicu bya molekile.
Ingano ya aside c-HCOOH mu gice cy'imbere cy'umubiri ni 6% gusa by'ibigize isomer ya c-HCOOH, kandi inkomoko yayo ntiramenyekana. Aha turasobanura ko c-HCOOH iri mu bicu byijimye bya molekile bitewe no gusenya no kugabanya c-HCOOH na t-HCOOH mu gihe cy'ingendo zirimo HCOOH n'uturemangingo twinshi cyane nka HCO+ na NH3.
Twakoresheje uburyo bwagutse bwo kubara ingufu zishobora gukwirakwizwa mu nzira za c-HCOOH na t-HCOOH zo kugabanuka/gusiganwa. Ibipimo rusange by'umuvuduko n'ibipimo by'amashami byabazwe hashingiwe ku nyigisho y'impinduka n'imiterere y'ikigereranyo cy'ingenzi mu bihe bisanzwe bya ISM.
HCOOH irangirika iyo ihuye na HCO+ mu gice cya gaze igakora isomeri eshatu za HC(OH)2+. Cations zikunze gukoreshwa cyane zishobora gukorana n'izindi molekile zisanzwe muri ISM, nka NH3, mu ntambwe ya kabiri yo guhindura 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 ibyagaragaye kuri 6%, turasaba gutekereza ku bundi 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.
Kubwibyo, HCOOH ishobora kunyura mu mpinduka twatanze mu gihe cy'ibicu byijimye bya molekile. Ubu ni uburyo bushya muri isomerism ya molekile za organic muri ISM, bushobora kugerageza gusobanura isano iri hagati ya isomer za molekile za organic ziboneka muri ISM.
