Oxirane ir absorption
WebSpectra for the structure I hydrates of oxirane and H 2 S contain absorption bands produced by guest molecules confined to both small and large clathrate cages. Use of the structure II double hydrates has permitted the firm identification of the structure I infrared bands with oxirane and H 2 S molecules in cages of one size or the other. Thus ...

WebConversion rate was analyzed using FT-IR spectroscopy by measuring the concentrations of ester, carbonyl, and alcohol groups. Moreover, oxirane-ring concentration was estimated … Oxiranes, also referred to as epoxides, are organic compounds in which an oxygen atom is bonded to two adjacent carbon atoms, forming a 3-membered ring. The three-membered ring in oxirane is highly strained and readily opens under mild conditions. This property is extensively used in organic synthesis.
