摘要:
用NMR数据解析方法对8-异戊烯基黄酮醇苷类化合物朝藿定C(Epimedin C)的结构进行研究.联合应用一维NMR(1H NMR\13CNMR\DEPT)和二维NMR(1H-1HCOSY\HSQC\HMBC)技术对朝藿定C进行归属指认.朝藿定C所有的1H和13C NMR数据(包括异戊烯基和糖单元),得到了详细解析和全归属,其结构得到了进一步确证.为该类化合物异戊烯基和糖单元的结构鉴定提供了可靠的解析方法.
Abstract:
The ultraviolet and infrared optical properties of glasses were studied when BaF, was substituted byBa(PO,), in fluoroaluminate glass by ultraviolet and infrared spectroscopy methods.Research indicates that,the introduction of Ba(P0, ) , can reduce the scattering and the absorption of crystal defects in glass，and cau-ses a migration of ultraviolet absorption edge to short wavelength.However， due to the intrinsic absorption，the ultraviolet absorption edge moves to long wavelength again with the increase of Ba(PO, ) , content， and theglass with 1% mole Ba( P0,) , content has the shortest ultraviolet cut - off wavelength.The phosphorus - oxy-gen bond( P - O) vibration produces a strong absorption peak at about 4700 nm， and the vibration of P - O -H bond results in the absorption peak of 5850 nm，that cause the shift of infrared absorption edge to shortwavelength direction. Influenced by hydrogen bonds，the absorption peak of hydroxyl group shifts to longerwavelength，and obviously broadened，reducing the transmission of glass in 3000 ~ 4000 nm scope.
