Melting points were determined using a Fisher-Johns melting point apparatus and are uncorrected. Optical rotations were measured with a JASCO DIP-370 digital polarimeter. The UV spectra were obtained on a Hitachi 200-20 spectrophotometer, and IR spectra were measured on a Mattson Genesis II spectrophotometer. 1H and 13C NMR spectra were recorded on Varian Inova 500, Varian Unity Plus 400, or Varian Gemini 200 NMR spectrometers. 更新: 麻煩唔好直譯... 直譯不如唔好答...
最佳解答:
一般實驗程序 融點使用Fisher-Johns融點測定儀 未經校正 旋光度的測定採用JASCO DIP-370數位偏光儀 UV測定採用Hitachi 200-20分光光度計. 紅外線光譜採用Mattson Genesis II 光譜儀 1H and 13C 核磁共振光譜 採用Inova 500 以及 Unity Plus 400 , Gemini 200 核磁共振光譜儀
其他解答:
_ 一般實驗性做法。_ melting 點是堅定使用菲希爾約翰斯melting 點用具和是未更正。_ 光學自轉是measured 與JASCO DIP-370 數字式偏振計。_ 這紫外光譜是獲得在日立200-20 分光光度表, 和IR 光譜是measured 在Mattson 《創世紀》II 分光光度表。_ 1H 和13C 核磁共振光譜是recorded 在Varian Inova 500, Varian 團結加上400, 或Varian 雙子星座200 核磁共振分光儀。_
