Kit ma ki neno kwede rwom me COM isomers i ISM miyo ngec ma pire tek ikom chemistry ki physics pa yamo ki, i agiki ne, tekwaro pa molecular clouds.
Gin ma tye i c-HCOOH acid ma tye i cold core tye 6% pa gin ma tye i c-HCOOH isomer, ki kama oa ki iye pwod pe ki ngeyo. Kany wa tye ka tito bedo pa c-HCOOH i pol pa molecule macol ki balo ki dwoko piny pa c-HCOOH ki t-HCOOH i kare me ngwec ma kwako HCOOH ki molecule mapol calo HCO+ ki NH3.
Watiyo ki yoo me ab initio ma ki medo me kwano rwom me teko ma twero bedo tye pi c-HCOOH ki t-HCOOH ma gi turo/gi loko. Wel ma pe loko i wilobo ki jami ma poko poko ki kwano malube ki lok ma mako alokaloka ki kit ma rwom me rwom ma malo tye kwede i te cik me ISM.
HCOOH balo ne i kare ma gi rwate ki HCO+ i dul me yamo me yubu isomers adek me HC(OH)2+ cation. Cations ma pol loyo twero tic ki jami mukene ma pol i ISM, ma calo NH3, i rwom me aryo me loko c-HCOOH ki t-HCOOH. Kit me tic man tito kit ma c-HCOOH yube kwede i pol macol. Ka ki kwanyo yoo eni i tam, wel c-HCOOH ma rwate ki t-HCOOH onwongo tye 25.7%.
Me tito 6% me jami ma ki neno, wa tamo ni omyero ki tam i kom yoo mukene me balo HCOOH cation. Kit ma ki lwongo ni sequential acid-base (SAB) ma ki waco i tic man kwako tic ma oyot pa molecule ma pol i ISM.
Pi meno, HCOOH twero bedo ni obi kato ki i alokaloka ma wa tamo ni tye i te pol pa jami macol. Man obedo yoo manyen i kin isomerism pa jami ma kwo i ISM, ma twero temo tito wat ma tye i kin isomer pa jami ma kwo ma nonge i ISM.
