求翻译:Melting Points were determined using a kofler melting point apparatus and optical rotations were made on a DIP-181 instrument. Spectra were recorded with the following instrument. IR and UV spectra were taken in Perkin-Elmer 599B and Shimadzu UV-300 spectrometer.1H NMR,13C NMR and 2D NMR spectra were recorded on a Bruk是什么意思? 待解决

熔点测定使用 kofler 熔点仪和光学旋转了一倾角 181 项文书。用下列文书记录了谱。珀金埃尔默 599B 采取了红外和紫外吸收光谱和岛津 UV-300 spectrometer.1H 核磁共振、 13c NMR 和二维核磁共振谱录上与 TMS 为内标的布鲁克上午 400 英尺核磁共振和 HR 轰击和轰击数据得出垫-12 (70 e V)。柱层析和硅胶 GF254 为薄层色谱法,用于硅胶 (100-200,200-300 目网)。

熔点使用一台 kofler 熔点仪器和光学循环被确定在一个放在-181 的工具上被制作。光谱跟以下工具一起被记载。非和紫外光谱被吸收 Perkin 艾尔默 599B 和 Shimadzu 紫外-300 spectrometre.1H NMR, 13C NMR 和 2D NMR 光谱用 TMS 在一 Bruker 是-400 FT NMR 被记载由于内部标准和克罗地亚-EIMS 和 EIMS 数据在一垫子-12 被获取 (70 e V).Silica 凝胶体 (100-200, 200-300 网格 ) 为了 TLC 用于栏色谱学和硅胶 GF254。
