ISM chung i COM isomers hmuhmi zat nih hin gas pawl chemistry le physics kong le, a donghnak ah, molecule khuadawm tuanbia kong ah man a ngeimi thawngpang a pek.
A lummi core chung i c-HCOOH acid a ummi cu c-HCOOH isomer chung i a ummi 6% lawng a si, cun a chuahkehnak cu theih a si rih lo. Hika ah hin HCOOH le HCO+ le NH3 tibantuk a tam tukmi molecule aa telmi cycle chung ah c-HCOOH le t-HCOOH hrawhnak le zorternak in a muimi molecule khuadawm ah c-HCOOH a um ti kha kan fianter.
c-HCOOH le t-HCOOH rawhnak/a kalnak lam caah a chuak khomi thazaang phawtzamhnak tuaktan awkah a kauhmi ab initio lam kha kan hman. Global rate constants le branching factors cu thlennak dirhmun theory le a tlangpi in ISM dirhmun tangah master equation phun cung ah hram bunh in tuak an si.
HCOOH cu gas tthen ah HCO+ he an i pehtlaih tikah a rawk i HC(OH)2+ cation isomer pathum a ser. A tam bik cations pawl cu ISM chung i a dang a tlangpi molecule pawl, NH3 tibantuk he c-HCOOH le t-HCOOH thlennak caah a pahnihnak ah an i pehtlaih khawh. Hi thil kalning nih hin a muimi molecule khuadawm ah c-HCOOH a chuah ning a fianter. Hi thil kalning hi ruah chih in, c-HCOOH le t-HCOOH tlukruannak cu 25.7% a si.
Report tuahmi hmuhmi 6% fianternak caah, HCOOH cation hrawhnak caah a dang lam pakhat ruah ding in ruahnak kan cheuh. Hi rian ah ruahnak cheuhmi a zulmi acid-base (SAB) mechanism nih ISM ah a tlangpi in a ummi molecule pawl a rangmi kalning aa tel.
Cucaah, HCOOH cu a muimi molecule khuadawm dirhmun tangah kan chuahpimi thlennak kha a ton lai ti a si. Hihi ISM chung i organic molecule isomerism chung ah lam thar a si, ISM chung i hmuhmi organic molecule isomer karlak pehtlaihnak fianter aa zuam men lai.
