Oke ndị a hụrụ nke isomers COM na ISM na-enye ozi bara uru gbasara kemistri na fizik 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 ọdịnaya nke c-HCOOH isomer, a ka na-amaghịkwa ebe o si malite. N'ebe a, anyị na-akọwa ọnụnọ nke c-HCOOH n'igwe ojii gbara ọchịchịrị site na mbibi na mbelata nke c-HCOOH na t-HCOOH n'oge okirikiri metụtara HCOOH na ọtụtụ molekul dị ka HCO+ na NH3.
Anyị jiri usoro ab initio gbatịpụrụ agbakọ nkesa ike nwere ike maka ụzọ c-HCOOH na t-HCOOH nke mmebi/ịgba ígwè. A gbakọrọ ihe ndị na-agbanwe agbanwe ọnụego ụwa na ihe ndị na-ejikọta ihe dabere na ozizi ọnọdụ mgbanwe na ụdị nke nha nhata ukwu n'okpuru ọnọdụ ISM nkịtị.
A na-ebibi HCOOH mgbe ya na HCO+ na-akpakọrịta n'oge usoro gas iji mepụta isomers atọ nke cation HC(OH)2+. Cations ndị a na-ahụkarị nwere ike imeghachi omume na molekul ndị ọzọ a na-ahụkarị na ISM, dị ka NH3, na nzọụkwụ nke abụọ iji gbanwee c-HCOOH na t-HCOOH. Usoro a na-akọwa nhazi nke c-HCOOH na ígwé 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 isii nke ihe a hụrụ, anyị na-atụ aro ka anyị tụlee usoro ọzọ maka mbibi nke cation HCOOH. Usoro acid-base (SAB) nke a tụrụ aro n'ọrụ a gụnyere usoro ngwa ngwa nke molekul a na-ahụkarị na ISM.
Ya mere, HCOOH nwere ike ịgafe mgbanwe anyị tụrụ aro n'okpuru ọnọdụ igwe ojii gbara ọchịchịrị. Nke a bụ ụzọ ọhụrụ n'ime isomerism nke molekul organic na ISM, nke nwere ike ịnwa ịkọwa mmekọrịta dị n'etiti isomers nke molekul organic dị na ISM.
