Oke ọnụọgụgụ nke isomers COM hụrụ na ISM na-enye ozi bara uru gbasara kemistri na fiziki nke gas na, n'ikpeazụ, akụkọ ihe mere eme nke igwe ojii molekul.
Ọdịnaya nke c-HCOOH acid dị n'ime isi oyi bụ naanị pasentị isii nke ọnụọgụ nke c-HCOOH isomer, nke a ka na-amaghị ebe o si malite. N'ebe a, anyị na-akọwa ọnụnọ nke c-HCOOH n'igwe ojii gbara ọchịchịrị site na mbibi na mgbochi nhazi nke c-HCOOH na t-HCOOH n'oge usoro ịgba ígwè nke gụnyere HCOOH na ọtụtụ molekul dị ka HCO+ na NH3.
Anyị jiri usoro ab initio dị elu gbakọọ ike nkesa ike nke c-HCOOH na ụzọ mmebi/nhazi cyclic t-HCOOH. A gbakọọ ihe ndị na-agbanwe agbanwe ọnụego ụwa na ihe ndị na-ejikọta ya dabere na ozizi steeti mgbanwe na ụdị nke nha nhata ukwu n'okpuru ọnọdụ ISM nkịtị.
Mbibi nke HCOOH site na mmeghachi omume na HCO+ n'oge usoro gas na-eduga na isomers atọ nke cation HC(OH)2+. Cations ndị a na-ahụkarị nwere ike imeghachi omume na molekul ISM ndị ọzọ a na-ahụkarị dịka NH3 na nzọụkwụ nke abụọ iji maliteghachi na c-HCOOH na t-HCOOH. Usoro a na-akọwa nhazi nke c-HCOOH na igwe ojii gbara ọchịchịrị. N'iburu usoro a n'uche, oke nke c-HCOOH ma e jiri ya tụnyere t-HCOOH bụ 25.7%.
Iji kọwaa pasentị 6 a hụrụ, anyị na-atụ aro ka anyị tụlee usoro ndị ọzọ maka mbibi nke cation HCOOH. Usoro acid-base (SAB) nke a tụrụ aro n'ọrụ a gụnyere usoro ngwa ngwa nke molekul ndị a na-ahụkarị na ISM.
Ya mere, HCOOH nwere ike ịgbanwe mgbanwe anyị tụrụ aro n'okpuru ọnọdụ igwe ojii gbara ọchịchịrị. Nke a bụ ụzọ ọhụrụ n'ime isomerization nke molekul organic na ISM, nke nwere ike ịnwa ịkọwa mmekọrịta dị n'etiti isomers nke molekul organic dị na ISM.
