中文摘要 | 2,1-Benzoxathiol-3-one 及 2,1-oxathiol-3-one 分別是構成 2,1-benzoxathiol-3-one-1-Spiro-1-(2,1-oxatiol-3-one) 的兩個部分,利用MNDO 分子計算方法,2,1-Benzoxathiol-3-one 及 2,1-oxathiol-3-one 的分子構形及其上的碳氧 bond order 可被計算出來,藉者比較2,1-Benzoxathiol-3-one 及 2,1-oxathiol-3-one 上的bond order,2,1-Benzoxathiol-3-one-1-Spiro-1-(2,1-oxathiol-3-one)分子上的四個 �噎NMR 吸收峰可以很成功的被提示出來. |
英文摘要 | 2,1-Benzoxathiol-3-one and 2,1-oxathiol-3-one are two moieties to construct 2,1-Benzoxathiol-3-one-1-Spiro-1-(2,1-oxathiol-3-one). By using MNDO motecular calculation, the conformations and C-O bond orders of 2,1-Benzoxathiol-3-one and 2,1-oxathiol-3-one have been calculated out. The four�� O NMR peaks of 2,1-Benzoxathiol-3-one-1-Spiro-1-(2,1-oxathiol-3-one) have successfully been assigned by the comparison of C-O bond order of 2,1-Benzoxathiol-3-one and 2,1-oxathiol-3-one. |
