Abstract Cyclobutene ozonide containing deuterium, 13C and 18O enrichment was prepared by ozonolysis of cyclobutene and via singlet molecular oxygen addition to furan. It was established that the ozonide has Cs symmetry. The structure was determined from the assignment of the microwave spectra of eight isotopic species. The peroxy bond distance of 1.492(5) A is increased by about 0.03 A compared with
摘要 通过环丁烯的臭氧分解和单线态分子氧加成到呋喃制备了含氘、13C和18O富集的环丁烯臭氧化物。已确定臭氧化物具有 Cs 对称性。该结构是根据八种同位素的微波光谱的分配确定的。与应变较小的单环臭氧化物相比,1.492(5) A 的过氧键距离增加了约 0.03 A。与环戊烯臭氧化物相比,环应变在其他几个键距和角度中也很明显。偶极矩为 2.857(2) 德拜。

Abstract The microwave spectrum of [2- 18 O] cyclobuteneozonide, a new isotopomeric species, has been assigned and the absolute direction of the dipole moment has been determined. The aim of this investigation has been to determine symmetric/asymmetric isotopomer concentrations in an arbitrary 18 O-substituted ozoneisotopomer mixture. The method we have used consists of transforming the ozone into cyclobutene
