ISM-a COM isomers abundance ratio hmuhchhuah te hian gas chemistry leh physics chungchang leh a tawpah chuan molecular cloud chanchin chungchang thu hlu tak a pe a ni.
Cold core-a c-HCOOH acid awm zat hi c-HCOOH isomer awm zat atanga 6% chauh a ni a, a lo chhuahna hi hriat chian a la ni lo. Hetah hian HCOOH leh molecule tam tak HCO+ leh NH3 te telna cycling process-a c-HCOOH leh t-HCOOH te tihchhiat leh anti-formation hmanga dark molecular clouds-a c-HCOOH awm dan kan sawifiah a ni.
c-HCOOH leh t-HCOOH cyclic breakdown/formation pathways te potential energy distribution kan chhut nan advanced ab initio method kan hmang a. Global rate constant leh branching factors te hi transition state theory leh ISM condition pangngai hnuaia master equation form hmanga chhut a ni.
Gas phase-a HCO+ nena inrem avanga HCOOH tihchhiat chuan HC(OH)2+ cation isomer pathum a siam a ni. Cations hman tlanglawn ber berte hian ISM molecule pangngai dang NH3 te nen step hnihnaah an inrem thei a, c-HCOOH leh t-HCOOH ah an lo piang leh thei a ni. He mechanism hian dark molecular cloud-a c-HCOOH lo awm dan a sawifiah a ni. He mechanism hi ngaihtuah chuan t-HCOOH nena khaikhin chuan c-HCOOH proportion chu 25.7% a ni.
6% hmuhchhuah sawifiah nan HCOOH cation tihchhiatna tur mechanism dang ngaihtuah belh kan rawt a ni. He hnathawhna atana sequential acid-base (SAB) mechanism rawt hian ISM-a hman tlanglawn tak molecule-te kalphung chak tak a huam a ni.
Chuvangin, HCOOH hian kan rawt transformation hi dark molecular cloud condition hnuaiah a tawk mai thei. Hei hi ISM-a organic molecule isomerization chhunga novel approach a ni a, ISM-a organic molecule isomer awmte inzawmna sawifiah tumna a ni thei.
