Di rεshכn dεm we dεn obsεv fכ COM isomεr dεm na di ISM de gi valyu infכmeshכn bכt di kεmεstri εn fizik fכ gas dεm εn, ultimately, di histri כf mכlikul klawd dεm.
di kכntεnt fכ di c-HCOOH asid insay di kol kכr na כnli 6% pan di kכntεnt fכ di c-HCOOH isomer, εn dεn nכ no in כrijin. na ya wi de εksplen di prεsεns fכ c-HCOOH insay dak mכlikul klawd bay di dεstrukshכn εn rεdukshכn fכ c-HCOOH εn t-HCOOH di tεm we saykl dεm we involv HCOOH εn rili bכku mכlikul dεm lεk HCO+ εn NH3.
Wi yuz wan ekstend ab initio aprɔch fɔ kɔl di pɔtɛnɛshɛl ɛnaji distribyushɔn fɔ di c-HCOOH ɛn t-HCOOH brɛkdɔwn/sayklin path dɛn. Globɛl rɛt kɔnstant ɛn branchin faktɔ dɛn bin kɔlkul bays pan di transishɔn stet tiori ɛn di fɔm fɔ di masta ikwɛshɔn ɔnda tipik ISM kɔndishɔn dɛn.
HCOOH de dεstroy pan intarakshכn wit HCO+ insay di gas fεz fכ fכm tri isomεr dεm fכ di HC(OH)2+ kεshכn. di mכst kכmכn kεshכn dεm kin riak wit כda kכmכn mכlikul dεm na di ISM, lεk NH3, insay sεkכn stεp fכ kכnvכlt c-HCOOH εn t-HCOOH. dis mεkanism de εksplen di fכmeshכn fכ c-HCOOH insay dak mכlikul klawd dεm. we wi tek dis mεkanism in kכnt, di prכpכshכn fכ c-HCOOH rilitiv to t-HCOOH na bin 25.7%.
Fכ εksplen di ripot 6% כf di obsכbishכn, wi prכpos fכ tink bכt wan adishכnal mεkanism fכ di dεstrukshכn כf di HCOOH kεshכn. di sikεnshal asid-bεys (SAB) mεkanism we dεn prכpos insay dis wok involv wan fast prכsεs fכ mכlikul dεm we rili kכmכn na ISM.
So, i go bi se HCOOH go ɔnda di transishɔn we wi bin prɔpos ɔnda dak mɔlikul klawd kɔndishɔn. dis na nyu apכch insay di isomerism fכ כrganik mכlikul dεm na di ISM, we kin tray fכ εksplen di rilayshכn bitwin di isomer dεm fכ כrganik mכlikul dεm we dεn fכnshכn na di ISM.
