Abstract:Both undergraduate and graduate students in chemistry are generally introduced to nuclear magnetic resonance (NMR) spectroscopy as a structure determination tool focusing on 1 H and 13 C measurements. However, NMR has also become an efficient analytical instrument with various applications including routine food analysis and quantitative impurity determination. These quantitation possibilities are rarely encountered in university laboratory practicals, especially in combination with the measurement of other nu… Show more
