The situation becomes even worse for larger molecules, due to closely spaced rotational states and low energy vibrational modes. These broad spectra are not suitable for compound identification.作者: 一小塊 時間: 2025-3-24 12:09 作者: cancer 時間: 2025-3-24 18:52 作者: 可轉(zhuǎn)變 時間: 2025-3-24 21:17

As the insight into chirality-activity relationships steadily improve and, as a consequence, legislation of chiral drugs becomes more and more stringent, the development of precise methods for the determination of enantiomeric purities up to ee>99% is of great importance.作者: 小蟲 時間: 2025-3-27 05:44
